I'v heard there is going to be another dragonball series created liek dragonball/z/gt.
Is this true? and whats it going to be about?

i dont' know. This is the first time i actually heard bout it. Maybe i should try to come up with some info about this

I dont know, I havent heard about it, but if it is true, then I hope the animation and story would be nice.

nope, not true at all. The DB cash cow. is dried out of milk cash. However, I herd this from some ANN. So I don't know it it's true or not.
