Yeah, it's most likely bollocks, or a taste-test to see how the fans respond...
My personal take, as a massive fan, is that Indy is NOT like Bond, it's not a book, written and with a character in place already, before being filmed, which allows multiple actors to take the role and succeed or fail based on accuracy to the book, or previous actors, or other factors....Indy IS Ford, didn't exist before him, and ANY take over, by ANY other actor, will be compared to some of the greatest films in film history (the first three..), and won't come up shining....
The best (only?) way to have made it work, would have been to have the last film "hand off" in someway, to an Indy in between the Chronicles of Young Indiana Jones, and Temple... And that would have perhaps worked, since those years, we CAN add in a new actor/face and pretend it's Ford, and then if the story worked, it would be fine to keep running with that actor....
But no, rebooting? No one needs that....If they saw the game success, and thought "oooh MONEY to make" then they need to remember that it's BECAUSE that game shows FORD, at his BEST, that it works so well.....We KNOW Indy, and want the years filled in with background in his PRIME, and that? Means games are the best (and only) way to proceed.....They should have done so a few years ago....With Ford's voice and Williams musical talent, and hell, Lucas and Spielberg writing too....But they didn't....They made Crystal Skull, and Dial, and neither showed fans an Indy we were ok with seeing...(Dial's opening was fun...)
Games...Not a reboot....Stop rebooting the greatest movies ever. Reboot failures, and work on THEM....Please...LOL
