To be honest i know i sound now like a cooperate sonyslave but seriously bloodborne is all i need this year. Edge couldnt even finish the game in 40 hours so bloodborne is probably an 80h game.

Does it really matter not having uncharted 4? The game will probably have a 10-12h campaign and thats it and the rest you can spend time on the multiplayer which wont be as exiting like the campaign. Bloodborne on the other hand will take longer to beat than uncharted and the order together thats for sure. That should be the game sony fans should be really cheering for all along.

Subjectively, sure. But objectively it is impossible to deny how massive a AAA franchise GT is for Sony. Even the Forza loving GT haters 100% know that GT is a big deal and an important franchise for Sony. The fact they would like to see it die forever is beside the point, in fact it somewhat reinforces the point. 

Uncharted is more important to Sony than GT as a foil against the more popular Xb exclusives, so it is there to compete for the soft market in that space. But GT has stiff competition with Forza and it is equally vital that Sony has a racing sim to keep Forza at bay, and of course to compete with PC racing sims. You might not rate the racing market, but it is an important market segment that needs AAA attention.

I do think that for 2015 in particular if you asked me whether it would be better for Sony to release Uncharted or GT7 (if they could only release one) I would say Uncharted, purely because of the line up MS is putting together for the holidays. But GT7 would be a highly acceptable alternative now that Uncharted is off the table.

Not first party, read OP.

Aren't people expecting exactly this from MS at E3 though? MS can do it but Sony can't?

Or are people only expecting big announcements for 2016 and beyond from MS at E3?

I'm not expecting any big announcements from MS. I mean I'm sure both Sony and MS will have game announcements, but not new one's that will also release in 2015. 

I know that. I'm saying I personally don't care as long as Persona 5 is released in the West this year.

But for the question's sake I'll say Guerrilla's new RPG will be revealed this E3 with a holiday release date.

Given Guerilla has mostly done FPS in the past if they produce an Elder Scrolls like FP RPG that will be an extremely poor substitute for UC4 from my perspective. But if they do it right and do it well then it could be a deent substitute for a lot of people.

Realistically only God of War 4 and Gran Turismo 7 can substitute Uncharted 4.

Also, I'm pretty sure Guerrilla's RPG will probably be third person. I could be wrong, but I honestly doubt they'll go first person for their RPG.
