The Simon and Schuster website has been updated with some new listings: The next New Frontier book will apparently be Resolutions, in January 2011. And in November this year we can expect two books by Rudy Josephs of a new Starfleet Academy series, described as "A new Starfleet Academy series for teens--filled with romance and adventure!"
The big question for me is; who's Academy? My first thought was that this was a nifty way to cash in on the new movie's young Trekkies, who will be eager to know more of the Academy days of the Kirk and co they know (and saw in the Academy) from said movie. Of course the recent new movie novel cancellations somewhat throws that out, but; the Academy days in the alternate reality are perhaps a safer playground for new material than stories set after the movie itself (and thus could be less likely to clash with the next film)... Another issue with this theory is the series page for these new books describes: "The voyages of the classic Enterprise, featuring Kirk, Spock, McCoy from the first TV series and the first six movies, set in the 23rd century." However that page also lists William Shatner's Academy novel, so could be out of date... Who knows? Not I!
