T-Mobile Sidekick III Roadmap?

Engadget has up what they are claiming to be a new roadmap for the T-Mobile Sidekick III (CRChair and I are owners and big fans of the Sidekick II, which lets us e-mail and surf the web from pretty much anywhere there is a T-Mob signal). If true, what is in store for the future?

...they’re planning to introduce a music-centric Sidekick III in April of next year and a second version with support for UMA (aka Unlicensed Mobile Access, a standard for seamlessly roaming back and forth between GSM cellular and WiFi networks — it sounds like T-Mob might be taking advantage of all their hotspots) in September of 2006, with Sidekick III limited editions to follow a month later (just like how they intro’d two limited edition versions of the Sidekick II last month). The next Sidekick after that, which is supposedly code-named the “Sidekick NG”, is listed as being set to drop in June of 2007. The Sidekick NG will supposedly have support for music, video, and UMA...

Does not sound convincing to me - and I was REALLY hoping for bluetooth capability to make use of wireless headsets. But you never know. Having an SK powerful enough to do Video and use WiFi would be quite nice, however... assuming it is still battery-efficient enough to go several days without recharging.
