I'd like to get excited, but I know that this will end up being one of those things I pretend never happened, just give us DK3 already! I don't really see how it'll work as a MMO, unless they do it sort of like Planetside, where underground you have the armies competing for space to create the dungeons, (in third person though).
I have to play some DK2 now, luckily I thought to put it in a special place and I still have it, bwaha! Unfortunetly DK1 doesn't work anymore, it just screws up and mouse sticks to one side of the screen.
