Well Blazing said most of it anyways
my opinion for reply to this thread lol
Well no we won't have new transformations YET here is the reasons
We are on Alpha Stage (There might not be a future if the dev's decide to give up)
People wishes allot for new transformations but you may forget the part that there will be unbalanced between race (Yes it's not a easy thing to add new transformations for other races it's like adding a new item to the game bug everything up cause of that 1 small thing)
If there will be new transformations then you have to wait for OB Lvl 70+ And hope for the Shenron to grant you're wish to become true
