BGR whispers that they're hearing that T-Mobile US will carry 8 HTC handsets in 2010. Specifically, it's 8 SKU's and that's including current devices too, so they're counting the T-Mobile myTouch 3G, myTouch 3G Fender Edition, and the HTC HD2 in the 8. Which leaves room for 5 more HTC devices that almost certainly come from this leaked HTC 2010 product lineup. Unfortunately, the 5 devices will be split between Android and Windows Mobile, so we shouldn't expect 5 brand new HTC Android devices just yet.
We're unsure if the Nexus One counts, considering it is made by HTC and runs on T-Mobile but since it's only sold by Google, yeah, who knows. Either way, it's nice to be re-assured that hot HTC Android devices are coming to T-Mobile.
