Yeah, CanonRumors speculated they could be bringing an STM version. That'd make sense, STM and newer IS. Maybe 15-60mm.
No way you'll see a 15-60 2.8 USM or STM. It would be too big, too heavy, and too expensive.
STM is for lower end $300-$600 lenses not for premium $1000 lenses like the 17-55. Ring type USM is much better for stills because of the real full time manual focus and distance scale. (and no one likes the laggy focus by wire)
I love all my STM lenses, but only because they are sharp and because STM is better than Micro Motor or Micro USM.
I suppose it is possible they might release a new a 17-55 STM version for video, but I would expect Canon to continue with the 17-55 USM or maybe even an updated 17-55 USM II.
