mortal kombat armageddon will NOT be online for wii AT ALL. a later MK title might though, they cannot encrypt online play through a firmware update. guitar hero 3 is not fully online for any console YET. maybe later on, but right now there is no confirmation of full online, only downloadable tracks and leaderboards have been announced so far, thats what i expect for gh3 since those are the only online capabilties for gh2 on 360, plus xbox live is much more developed than wii online. also whoever posted wikipedia links(cough *minismok* cough), dont ever trust wikipedia for reliable game news, check ign or the game's official site. wikipedia is just not a good place for unreleased game news.
