Better technology on its way?

Just wondering if anyone is aware of any new technology on the horizon that look promising in regards to hair removal. I recently came across this article on lasers and thought I would share it:

Maybe more precise laser technology like this could be used for hair removal and better permanent results could be achieved.

how about the new one that destroys hair by sound [dont know the name] seems a bit SUSPICIOUS to me, personally…

has anyone else heard of this too?
