I don't think we'll see a reboot until the current run of shows (the Kurtzman era) is done. Right now, all the planned shows seem to be in the same continuity and timeline as The Original Series. Maybe, as the final Kurtzman show is dying down, and Kurtzman himself having long left, some bigtime creative fan of Star Trek will propose a reboot, a la JMS's post-Enterprise reboot proposal, and CBS will give it a go. More likely, there'll be a hiatus of a few years and Hollywood will have to enter a "reboots are cool" phase. Right now, with Netflix and fan nostalgia, sequels and continuations are the big thing, with Star Trek being a beneficiary of that goodwill. Reboots aren't as well-liked, at the moment. Charmed and Roswell, notwithstanding.
