I think you're missing the point. It's not because its exclusive, at least not for me.
It's because its Insomniac. I don't care much for Xbox exclusives because I've never played those franchises before. They weren't previously on PlayStation and the new and upcoming exclusives won't ever be on PlayStation so why worry about it?
But I've played Insomniac games since the PS2 days and absolutely love the developer. I wish them tons of success with this game. Doesn't mean I don't wish I could play it on one of the two major game systems I use. Last I heard that Ratchet game was essentially a glorified movie tie-in. It's a complete retcon of the story. Until I see more, I don't see the point in pointing that one out as if throwing PlayStation fans a bone is enough to distract from the fact that I'm not able to help support a company I followed for ages. Business is business, and I'm not upset at them for taking this chance. It's the best offer they could have gotten. It'll be great to see how it helps them grow.
Plus, the original question was "why is this so long on something so silly". I can assure you, to PlayStation Insomniac fans, it isn't really all that silly to hope for more chances to play their next game.
woah woah bro I'm with you....Insomniac were my favourite dev too (not anymore), bur Ratchet and Clank is more than a bone. Insomniac were my favourite developer because of Ratchet and Clank and Spyro, a continuation of Ratchet on PS4 is definitely more than a bone, its the meat to me.
I really hope though thats its not just a glorified movie tie in and in fact expect it not be. I expect very big changes from RC 1 to RE Redux (got to say the creations of two alternate universes is not something I like) since the movie trailer showed it was very different to RC1's story. Ideally we would be getting a brand new RC trilogy on PS4 but I'm going to be patient for now. I heard the original team are working on it so I expect great things.
Sunset Overdrive weaponry reminds me a lot of RC, though it lacks the stuff that made RC so special to me: the charming characters, adventurous story, actually being funny, exploring the dozens of planets and their vista's , a great blend of platfoming and shooting, oh and the OST. RC was....imaginative and I loved it as a kid.
