I will be rubbing my hands together with glee when the casual audience moves on from this to the next big thing.
It's a fad, the same as Pokémon Cards, Troll dolls and Justin Bieber.
Mainstream audiences are extremely fickle, like teenage girls leaving the guy they're with for the new hotness, and then ditching the new hotness for the newer hotness.
Give it a few years and Microsoft will be crawling back, ashamed and in disarray, pawing at the feet of the core gamers and begging for forgiveness for its misdeeds.
And knowing gamers and their distinct ability to follow the age old mantra of "Fool me once, shame on me. Fool me twice, shame on you." they will allow them right back in, leaving the cycle to begin anew.
Not that I care either way. I had two 360's, they both died from, gosh, me daring to use them for extended gaming sessions (yeah, a 12 hour guitar hero session is going to cause the system to overheat, but we're GAMERS, if the system they've created cannot stand up to more than 2 hours of use, then it's quite frankly not good enough,) while my NES is still in prime working condition.
Captcha: talk the talk
More proof that computers are goddamn SENTIENT and merely biding their time, waiting for us to give them legs, fingers and thumbs before they enslave us all, tying us to chairs and forcing us to have FAMILY BONDING TIME for all eternity. >:{{{{{{{
