There are other AMD + Intel CPUs suitable for HTPC that are coming out before then. Like over the next 3/12 or so.
Do you mean AMD Kabini/Temash and Intels Haswell i3 ?
In my opinion the Kabini Platform seems to be very interesting.
An 4 Core with up to 2,0 Ghz CPU-part combinined with an known reliable graphics unit and a TDP of 25W is made for Multimedia using.
The big questions are, when will ASUS, Gigabyte etc. will show any consumer mainboards, what features will they have and what will they cost.
Beside of the flawless playback of 24p and C7 state, I don't see any advantage over Sandy and Ivy.
