How long will it take until this news is reported all over the net? Think about it, Quake I, II and III have already been ported. We will just see when Doom 3 and Quake 4 get their sources released, and finally Doom 4. Symbian OS is growing and expanding its capabilities all the time, and in the future it supports quad core (or even more) processor composition, so it's very likely that these games would be playable in the future devices.
Interesting to see what the future brings to us, eh?
