Like pretty much any other MMOs I will buy them and try them, even though I have like zero time to play. EQ2 will be the suck, basically it will be FFXI just with EQ characters.
WoW on the other hand sure looks promising, a guy I work with is in beta, and while there are any number of problems, their quest system seems to be nicely developed and actually rewarding when considering reward vs time, or reward vs risk.
Who knows, they still have to release either and short of trying it out there is no way to tell how good or bad they will really be.
