Sony hasn't said anything about funding the entire project. In fact, during an E3 interview, Sony was very coy about how long the timed exclusive is

If it was going to be years before the Xbox One gets the game then they would of said something. However, as for now, Sony isn't saying anything which probably means its going to be a sooner than later. I would guess about a year.
As for Shenmue 3, Sony is only developing the port for the PS4 version of the game. It's not developing the entire project. This is according to a twitter post from one of the producers.
Yes, but there has been Konami like turmoil from the development team of Last Guardian. Who knows if it's going to be the same quality as the previous games...
