I have a PS4
and don't play the "victim" people making that kind of partial lists to try to show only an angle that makes their argument or preferred console look better than it should happens on both sides of the arguments on this (honestly I was certain only xbox fans did this).
Anyway, your conclusion is obviously right, any list war should include complete list of games that had a proper reveal (I have seen lists of exclusives for the xb1 that included a Gears of War title that was barely mentioned, but as far as I know never even properly revealed, not even a teaser trailer).
So what should be in those:
Games that we know are in development, but were not revealed, can they legitimately be on? (Gears of War by Black Tusk for the XB1 and the unknown games the Sony studios are working on, Santa Monica, Studio Japan, etc.)
Games that only have 1 or 2 reveal trailers, do they count? (Uncharted 4 and Halo 5 by example)
Games that had a gameplay reveal, but it may not have been representative, should they be included? (just flashes, very few played behind closed doors)? (I think bloodborn and quantum break are in this category)
Games that do not have a set release date, are they concrete enough? (sometimes we feel a lot was shown, yet... no date)
We are left with the released and close to release games, these are concrete enough for most people to call fair, and any of these titles should be included, exclusive or not.
But in all cases there are intangibles, I guess you are an Halo far, I don't particularly like Halo... but I really like God of War, guess what, if there were 25 Halo games on the XB1 all running at 1080p 60fps it would not make me salivate as much as a God of War 3 remake :-/ and even less compared to a God of War 4 or some kind of descendant would make me go wild! This is my bias, and lists cannot account for that, if you offer someone something they want, you can offer them a million things they don't want in exchange that won't interest them.
