I second this. Have been trying to figure this out since the roadmap got leaked. It seems like this news either is getting neglected or no one has an answer.
As promising and appealing as this phone is, I would guess that it is the latter.
I think T-mobile will get it in April. The HTC product map shows this product being released in April. And in the past, the HTC product map has been very accurate with regards to product release dates.
