.....make wow 2? or do you think they will keep making expansions? or maybe just stop doing stuff after cataclysm?
personally i hope they stop after cataclysm and continue on to make warcraft 4 and a new lost vikings game. Maybe Starcraft: Ghost.

i hope never.... 
 
Do you think they will ever........... quit? I HOPE SO! :) no offence :) 

They will keep making expansions till the end of time.

No. That would be like saying "We hate money".

They've already started work on a new MMO, which is supposed to use a completely new IP.  Whether it sees the light of day or not, I guess depends on whether blizzard thinks it will make money.

Cataclysm pretty much is WOW 2.

" Cataclysm pretty much is WOW 2. "

Blizzard is making a new MMO on a new IP, so no. 
 
I'm also tired of fantasy, I want Sci-Fi or Cyber-Punk.

"Ever" is a very long time.  Few people are likely to forget the cashcow that was WoW, at least any time in the semi-near future.

I expect it'll happen, but by the time it does you'll be saying "It's about damn time." lol

I also want to point out that WOW will more than likely keep getting expansions for a long time. 
 
Everquest had an expansion come out last year, as well as another one planned. This isn't Everquest 2, this is the original Everquest that came out 11 years ago in 1999. The highest number of players ever formally announced was 450,000. Which, while a good amount, is nothing compared to WOW's 12 million.
 
EDIT: Actually, after looking up Everquest, they just had an expansion released 3 days ago! I'm gonna make a guess here and say that there will probably be another one next year as well.
