Well, two years in serious, OS X/iEra talk...it's REALLY ratcheted up, with patent drawings, etc. It actually, now, seems like something Apple might
do, vs. five or so years ago.
I realize it's been long desired, but it now drives serious, heated and breathless discussion and speculation.
I mean, when they go their longstanding pattern of secrecy and tight lips and pull the lid off an unreleased product MONTHS in advance (like the iTV), then you have to figure ANYTHING is possible now.
It certainly isn't the Apple of 2-4 years ago, is it? They're making good commercials, they're embracing TV (something people said Jobs would never do), etc.
