The October date should be firm as Revell USA had a fully painted final production shot on display at their table at the IPMS USA Nationals in Loveland, CO three weeks ago. Indeed it does look like scaling data from the previous Revell X-Wings was used, so there are some similarities. But in the flesh, it looks enough like an X-Wing that it can be made to look great even if all you do is slap a new coat of paint on it.
The proton torpedo ports are shallow because of how the mold was made and the draft angle of the parts, but that is a relatively easy fix. One cool thing on the kit though is you can dismount a portion of the belly tray, revealing a torpedo load. All you get inside are the torpedoes though and no other machinery, but a super detailer could go to town here. However, I suspect the REAL reason why Revell offered this feature though is you now have a ready made compartment to stick in a battery pack for a light circuit. This way, one doesn't have to carve in an access port.
All in all, I like what I see.
