Ask HN: What do you think about the future of virtual worlds like Second Life?

Second Life failed to live up to its hype, but still I could see a lot of Virtual World ecosystems that should be making good profit (like TheSims). So, do you think there will be any user acceptance around 3D ecosystems if enough effort and energy is spend around building Browser based players (WebGL etc) that's compatible with OpenSim etc? Thoughts?
