I wonder if we will actually see a revolution from the SLA side. Take a look at Slash, which is going to be introduced Soon (tm):

Printing speed is radically increased, since they use a different sintering mechanism (UV matrix is blocked selectively by LCD). Quality is stated to be about (?) as good as existing SLA.

If they can deliver, it would seem that FDM gets pushed out of the mid-tier of consumer market. They could still dominate the $500 device space, since Slash will initially cost $1500+ and might take a while before there is a credible competitor or the licensing begins.
