There is so much virtual worlds vaporware out there right now... I'm on the team that says, "I'll believe it when I see it." Every time I see a supposed "
SL killer" or even "perhaps a competitor", it really makes me appreciate Second Life all the more.
OpenSim is the closest thing out there for what I enjoy about
SL, and all of the people involved with OpenSim admit there is a LONG way to go!
