I feel like someone looked at a bunch of games that released on PS3/PS2 and either put the franchise name or placed a incremented number at the end.
I'm pretty sure Star Wars 1313 was cancelled.
My God that PS4 list is absolutely amazing. Persona 5, RDR 2, 1313, Uncharted 4 if this is true this E3 is going to be insane. But something seems off about all of this.
This list seems either insane or includes a lot of placeholders mixed in with the more likely few.
Can't imagine Persona 5 would skip the PS3 given Atlus' typically being behind a generation or so, but I guess that could potentially explain its total lack of any substantial info so far.
Guy on this board who was supposed to have inside knowledge mentioned DS2 was happening too though I'm highly skeptical as Dark Souls makes it redundant. That would be megaton to me.
The thing that you don't pay a single kr before the game is sent or you pick it up. You don't lose anything on it. So Webhallen has loads of games available for pre orders. Half life 3 for example. You have been able to pre order "xbox 720" and "ps4" for about 3-4 years now. I can't see how this is thread worthy.
Edit: They just guess with this stuff and have no more sources than anyone here. They add sequels to titles that where popular and may get a sequel.
