MMOFPS = MMORPG except with shooting gameplay/theme, your post is confusing
(constantly online, incredibly large server size, moments to chill next to real people rather then online just to fight, 1-few connected maps, not 5+ differnt levels)
I'm pretty sure no mmofps games are out right now, well 1 or 2 old ones that suck.
And yes by your desciption Counter Strike would be your idea of an mmofps, which it's not. Don't see how buying weapons and armour turns a regular online shooter into an mmofps btw just buy one for the PC if you so desire one. It realy seems like a lot of people have never played a PC game that can't be found on addictinggames. There are REAL games and pc is the ultimate for online/graphics/shooter (though 360 is pretty close for a console).
The Wii will get a few online shooters but it will not get a mmomrpg (atleast no time soon, and/if when it will be limited) let alone a mmofps, making one with no lag is incredibly difficult on the pc let alone a console. However if you want more appropriate online console titles like sports and racing then just wait for them.
