With the announcement of Air Play in new OSX Mountain Lion, there is absolutely no way that Apple is going to drag down the rest of it's 1080p(or better) resolutions for it's entire product line. Apple has to know that there will be a ton of 1080 ATV3 sold so that mirroring from the Mac to the TV won't be totally degraded. I don't think Apple will be so dumb as to only offer this only with a $2000+ 42/46/55" TV. I also think that's why Tim Cook announced the number of ATV units sold in the 4th quarter for the first time. Mountain Lion is coming out this summer, so I'm predicting the bottle neck in the whole system(ATV2) will be gathering dust by then and a new ATV3 will be rolled out. Perhaps it will come as soon as the iPad 3 announcement.
