Well...personally I'm confused, for one and one reason only.
Smo is on the team. Smo has made a much more precise version of Goku, and a much prettier version of the SSJ model in particular, with the hair being a lot closer to the "real" shape of Goku's golden afro of awesome power. So...
...why doesn't the team just include that model, and any other updated ones, in Beta 1.2?
