Yes. As far as I know, and please correct me if I'm wrong, this was the first time that a Kickstarter game was featured in an E3 presentation of a platform holder and there are some questions about said platform holder's participation in this project. In my opinion this case deserves extra scrutiny. It may also be the first case of a platform holder buying exclusivity of a Kickstarter game before the campaign is even announced, though there is no way to be sure at this point. That also deserves extra scrutiny. I understand this may be hufely frustrating to Shenmue fans but this is why I said earlier on this thread that Suzuki got screwed.
I haven't seen a lot of Kickstarters, but from what I saw, normally a Kickstarter game would focus on one platform (mainly the PC), as it's easier to allocate resources and much cheaper to focus on solely one platform. Publishing a PC game is also far simpler than publishing a game for a console (from what I heard). Other platforms may be announced as a stretch goal, but the development focus would be on that one main platform.
Had Sony not step up to strike a deal with Suzuki, the latter might have still gone with a Kickstarter campaign. He has been vocal about it and it seems that he was going to push through with it with or without Sony's help (in fact, he even approached Microsoft but got turned down). What would have happened is that the development would solely happen on the PC and will completely disregard any other console until the game's release or only if a stretch goal is achieved. Don't completely forget that while 2 million is absolute minimum to have this game funded, Suzuki hopes to get 10 million to match this game with his vision, which is normally the case for Kickstarter campaigns (hence, "Director's Cut" is normally a stretch goal as well). I doubt 2 million is enough funds for Suzuki to create this game for the PC
and the PS4.
My point is that Sony's aide primarily guarantees the production of a PS4 version, and their funds
could just be enough to cover the PS4 port. This removes a lot of from Suzuki's plate. He can use whatever he gets from the Kickstarter to focus on developing the game itself, while he can leave the rest to Sony to port the assets to the PS4. Essentially, Suzuki will be earning from a PS4 version aside from the (potentially) PC(-only) version without having to bite his nails over it. Again, we don't know how much Sony is giving, whether it is enough to guarantee console exclusivity or just to have a PS4 version made, but I think it's a bigger stretch to say that the game would have been released in other platforms aside from the PC if Sony had not stepped in to help production, considering the funds and all.
Again this is all speculation and it really doesn't help anybody. There is case for skepticism definitely, but that Suzuki and Sony have tried to be open about each other's involvement as they can. It's up to you choose be skeptical after, but don't push that skepticism on people who see nothing wrong with the set-up.
