Wow EdStation3 you spout out all the false info that is now old and disproven.
MS has a history of ending support early. You base that on 1 previous console and if you paid attention to history you would know that MS knew that the Xbox hardware would never sell at a profit. While the last 3 years the 360 has sold at a profit. Xbox had 4 year lifespan and the 360 has already entered its 5 year with no replacement in sight.
Devs will abandon the 360 because of DVD. So you have the HD console that sells the most software and will hit 50 million console penetration in the next year plus. Lets see is it a good decision to leave that market when that market is where you sell more software. Just so you dont have to compress a game or put it on multiple DVDs. Year right, that would be a sound business decision.
Not to mention it is looking more and more likely that the PS3 is just not going to pass up the 360 before any new consoles get released in 2012-2013. By the time price adjustments happen on the 360 the PS3 will still be 6 million behind the 360.
Its libraries that sell systems not a single game.
