The thing is, there is already plans for extra transformations for ESF 1.3. This has been brought up numerous times in the past, and is one of the reasons I stopped posting here, mainly for the repeated posts about extra transformations, and character additions.
Here's the deal. Extra transformations are already planned, and are probably already implemented by now (just needing models), and every character will have all his/her transformations (Goku's SSJ-SSJ3 [Not SSJ4 as that's GT], Piccolo's transformations after fusing with Nail, and Kami, and all of Cell's forms.)
