What servers would they have to upgrade?
There is just a master server for server queries.. You don't need much for that. And you can donload th patches from fileplanet which would take days of waiting in line.
They wouldn't have to upgrade anything..
Besides.. If you show me a screen shot of more than 1000 players in either game I will give you an e-cookie.. It isn't going to happen..
People are more interested in MMORPGs, UT, Halo, and HL mods.
