Spider-Man Miles Morales will be a system seller for me, and there were a couple of cute indie games here and there - but doubtful that any of those will be PS5 exclusive.
On another note, that console is UGLAY. It is not a pretty looking console by any stretch of the imagination, and my girlfriend and I literally burst into laughter when the whole thing was showed off. It literally looks like my the tower fan that I have in my livingroom.
Sure, the Xbox Series X might be a big boring cube, but at least it is neutral and inoffensive. The PS5 looks so horribly alien, and like a fan-made concept someone thought the PS3 would look like.
Otherwise, im pretty surprised by the lack of pricing, so I guess Microsoft and Sony will just be waiting each other out, so that the other can undercut them.
