You forgot Axiom Verge, Rime (yay cute exploration) oh also Hellblade and No Man's Sky.. just some possibly well received indies that are likely coming out in 2015!
And underestimating many of the titles you put in your list.
We shall see how it goes, this is all in the execution of the concept, rating a game on "it's linear" or "open world" before even experiencing it, it makes zero sense, nobody would need reviewers if you could just read the list of features at the back of the box, watch 2 minutes of gameplay then go and give a qualified note of your appreciation of a specific game.
Anyway, that would be a sad year if the best received exclusive game had a metascore of 89, this is not to disparage the game or imply 89 is somehow not an amazing metascore, it may very well be one of the great games released this year... I just don't think it will be the best received game.
