You could make the argument that medium capacity systems, or mini-metros, are growing in popularity. I don't know if that would translate to "ICTS is the wave of the future, 20 years from now we will use induction motors to go the the bathroom" but it is a start. Copenhagen's new metro, the Turin metro, Dubai's planned system, some of the new Moscow lines and Hong Kong lines are all mini-metro esque. So is London's DLR (despite the name), which has been expanded quite briskly. Even Tokyo's been building some.
I would support RAV like service in Toronto. The only reason I dislike the SRT is because of it's motors.
*By mini-metro or MCS, I mean a system which is ideally automated, running in shorter train configurations (~4 cars), with narrower rolling stock an on narrower guide ways. Rubber tires common.
