Over at "Total Mobile" you can read, that T-Mobile (UK) will release two new Windows Mobile devices by Christmas this year: the MDA Vario (which is the HTC Wizard) and a new - so far unknown Windows Mobile device - to be called " MDA compact II".
According to own inquiries, the MDA compact II will will has the same size as today's T-Mobile MDA compact has but - and this is the most important part - the new MDA compact II will use Windows Mobile 5.0 instead of Windows Mobile 2003 Second Edition and will includes W-LAN! Therefore it cannot be the Magician at all (since the Magician hasn't has sufficient memory to run Windows Mobile 5.0 nor it has W-LAN capabilities) but must be a new, unknown device. Either from HTC or it might be the same device from Quanta, which O2 is going to introduce as O2 Xda Atom soon.
At this time, I haven't received more information but the information, that the new compact will has Windows Mobile 5.0 and W-LAN seems to be trustworthy.
