If you go back and see what they announced last year, you'll get your answers.
err, the only X1 exclusive confirmed for this year is Sunset Overdrive. Seriously, why am I the only one noticing this?
Because some people have their goggles on too tight. For everyone "concerned", I wouldn't worry, WW Sony will still easily outsell MS and likely they'll also do so in NA (we will have a better idea in the coming months).
For sales, sony only needs the big multiplats, some of you guys seem to think games like Forza and SO are going to light the world on fire. Hint: they're not, TF didn't. Sony will be fine, sales wise
Now, personally this is pretty disappointing, but if it makes the game better then fine. I was really lookong forward to this as the big Fall game (for me), but at least late 2014 is still plenty packed. 2015 is going to be great.
