The problem with folks around here is that you guys think everyone is like you. If everyone was like you, Wii would not have sold 100 mil+ and dominated the 1st half of last generation.
If everyone was like you, Wii's 480i/p res would have mattered... the PC would be the lead and dominant platform for every single 3rd party game, including EA's sports titles... Call of Duty would not be the #1 seller... Just Dance, Skylanders, Mario Kart, 3DS, etc. would not have dominated the charts.
Some multiplatform games will be 720p/720p on xb1/ps4, some will be 720p/900p, some 720p/1080p, 900p/1080p, and a bunch 1080p/1080p. Will it matter? To the hardcore, sure. To the soccer moms, to the kiddies, to the dude bros... not a chance.
It's not a question of power or specs or fanboy wetdream wars. It's a function of simply how many resources Microsoft is willing to invest to get to 30%, 40%, 50% or whatever market share their ultimate goal is. My bet is they are going to be willing to spend whatever it takes to be the market leader in this segment because the stakes are higher than ever and the value of the piece of pie they are after will potentially return more than ever before (because now we're talking *real* revenue from services on top of games... we're talking a digital pie that includes the itunes, the hulus, the netflix's, the digital games and apps downloads, etc., and more things in the future like ipTV, phone/skype dominance, etc.).
They will money hat as many exclusives as necessary... they will open as many studios as necessary.. .they will bundle and price drop as much as necessary... they will break as many fanboy hearts as necessary to beat Sony and, by relation, you the Sony holdout dreamer. Your salty tears and hate will simply fuel their fire. You will try to vote with your wallets and your voice, but your wallets/voice will get trampled by the XB1 gravy train laden with the soccer mom's and dudebro's hooing and hawing their way to a connected, metro-interfaced future.
You will lose. In fact, you have already lost.
