I think this might answer your question DL4567. I had to remove a LOT of personal comments from this one. It tells me there is a lot of scrambling going on over there because a lot of "eyes" are on this. If nothing else it will help the product but a few things went too far (and maybe too quickly) and unfortunately they rushed at pouring the foundation. Latest update...
SDCC graphics were roughed out at Mattel and 'cleaned up' in Asia so there would be something ready for Comic Con. The SDCC board was just a stand in. The graphics were just a print out from the plotter and mounted to the boards. The team was told specifically to show some 'progress' since the NYTF board.
These are not meant to be 'excuses' (there are none) but rather explanations. Since the sculpt is fixed, meaning the recessed channels for the pink velcro is fixed, the graphics have to derive from that. Looking at many screen shots and screen used boards (including Bob's) there are slight differences in each one. Some differences are 'major'. Angles of the bands (pink, white, yellow, green, even layout of lenticular bubbles) vary from board to board. The problem with having 20-30 props to choose from is which one do you use as a master. The more research you do, the more differences you will find. We were told that almost each shot of the boards (Marty's, Griff's, Data's, Whitey's, Spike's), it was of a different board. When the BTTF production team spoke, we had to take notes, and then follow up with the production board.
Complaint: yellow bands are off. The pink overlaps the yellow on the bottom, creating a 'quadrilateral' instead of a 'triangle' (lower right corner). SDCC has this 'problem'. Well, there are screen shots of a board that also has this 'problem'. Band angles are another problem. Not only do they vary from board to board, but some seem 'more parallel'. Anyway, the size and angle was adjusted to show less 'overlap'.
Another complaint, the lettering was really rough. The lettering was soft and rounded, as if someone traced it in Photoshop. Lettering has been fixed, totally redone. Basically, retraced in Illustrator with crisp edges. Again, there are many slight variations on the lettering on the screen used boards.
The lenticular 'bubbles' are another thing. While there is little to no hope of getting real lenticular, the board will be some "foil printing" that is suppose to look close to the lenticular. The sizing, shape, and angle of the bubbles are being reworked to match Bob's boards (which were photographs of lenticular). They are trying their best at this.
While not 'perfect', these updates are way better. That being said, there is no guarantee that somewhere along the line things do not get messed up. This is already late and the graphics needed to go out today for development. So, now it is a waiting game until the FEP's come in.
Bevels: It should be about a 0.20" bevel, 0.40" flat, 0.40" bevel on the 1" thick board. The SDCC board is split in half, about 0.5" and 0.5". Top is radius, as stated. Because of the 50/50 split, it only leaves about 0.2" of 'flat' for side graphics. Possible solution is to cheat the graphics taller, not sure if this will be fixed. Bottom bevel is at about 0.5", which makes the label smaller...while making the hardware look even bigger than it already is.
Red Mounts look 'short'. There should be about 20% more 'meat' on the flat parts. Looks like the red mounts are duplicated for top and bottom discs, just like the screen used. Remember I mentioned that the bottom mount does not kick up with the board? There is a step from the board to account for the kick of the board. On one of the SDCC boards, the screw holes had a raised lip, about 0.1".
Mag Discs: There is a lip on the silver disc. That inner lip should be were the black bevel starts. But, there is about 0.35" lip before the black begins. I think this has to do with bigger surface area for gliding. Because of this extra lip, all the hardware is sized up to match it. This also causes the red mounts to be 'short', overall length from tip to tip of red mounts is about right. Since diameter of discs are larger, this makes red mounts short, and all hardware look bigger and wider...does not make sense?
Battery Pack: Again, larger due to up-sizing of hardware, and possibly to fit the batteries. Also missing a 'counter sink' for the screw holes, possibly to fit batteries.
We all hoped for at least a 9/10 on this. I think because of certain limitations and 'directions', the best we can hope for at this point is about 7.5-8/10.
For comparison, I believe the Nike Mags are a 9.5/10...even without the power lacing. There are some things that are just a tiny bit off from screen used. Thing is, according to Tinker Hatfield, they restarted the project three times. Nike did not have the overhyped marketing that Mattel has. They had everything made, and then did some viral marketing. Mattel did (their version of) viral marketing, then tried to make the board to live up to the hype. I also know Nike 'lost' money on the mags after speaking with R&D employees. Mattel will be in the same boat with the hoverboards.
