More discussion of Virgin Galactic's plans to bid for NASA Commercial Crew Development funding in an article in Aviation Week:

“There’s about four companies that are seriously looking at [CCDev Phase 2],” Branson said in an interview with AVIATION WEEK. “Two of those companies we’re in discussions with about teaming up with. ... Over the next month, we’re going to make a decision as to whether to team up with one of those two companies or go it alone, but we plan to be in orbital travel within the next few years.”

Since Space Adventures has already linked up with Boeing for passenger launch on the CST-100 capsule, there is speculation that Virgin is talking to SpaceX, and to Sierra Nevada Corporation (builders of the Dreamchaser spaceplane). Virgin may also be looking at resuscitating the airlaunched concept designed by Scaled Composites for T/Space.
