As HTC Europe announced today, T-Mobile International, Vodafone Germany and O2 Germany will launch the HTC Touch later this year; HTC's recently announced Windows Mobile 6 Profesional smartphone for the mass market.
While T-Mobile and O2 Germany will release the HTC Touch in its own exclusive IDs, T-Mobile as MDA Touch and O2 as Xda nova (see our extensive photo view of the O2 Xda nova here), Vodafone will release a co-branded version of the original HTC Touch design:

On the left the HTC/Vodafone ID, on the right the O2 Germany ID. The T-Mobile ID is unknown yet.

All three carrier plan to release their versions of the HTC late June/early July while it looks like O2 Germany is the first to bring the device to the market. Without a contract, the HTC Touch/MDA Touch/Xda nova will retail for around 450 Euro. Furthermore sources indicated, that it will be available subsidized for around 49 Euro.
With the exception of T-Mobile Austria, it's not yet known if other T-Mobile, Vodafone and O2 subsidiaries will launch the HTC Touch as well.
