I heard that Vegas 14 will only be bug fixes. Sony is going to fix every single bug that anyone can find and then they will release this as version 14. Free for owners of Vegas 12 and 13 and a nominal fee of $25 for all other Vegas users.
On a totally unrelated thought, I always thought the Movie Studio version of the NLE should've been called Reno. You know, similar to Vegas, but with fewer bells and whistles.
