Did we mention it's coming to T-Mobile? And it'll be sporting an HSPA+ radio to take advantage of T-Mobile's 4G network. Unfortunately, it won't be available until this summer.
Earlier, Mobile Bulgaria (which, as of this writing, is down) stumbled upon a Vodafone product page for HTC's upcoming dual-core Android handset, the Sensation (aka the Pyramid). Availability for Europe and Asia will be throughout Q2 - no exact dates have been announced.
