I don't see any other explanation than the fact that the market research Tamashii acquires ends up in quite a different line up then what the western market wants. Barring fanpoll choices.
However, no Vegeta except ssj4 was even ON their fan poll in america. How the **** is that fair? 'Majin Buu' was without specification, also not exactly great. I appreciate polling, but it's cheating to take fan favourites off the ballot. Nobody can contest that that is inconclusive market research.
I feel they wanted to make Vegito for conjoined domestic appeal and are now choosing to attach releases behind it that are connected to it, like making 16 after the twins. I applaud the essence of that thought and am convinced it's meant as costumer friendly, but the truth is... after 16 it isn't. Not within the context of this line. Vegito was not the right jumping on point for the Buu saga, nor are the connected releases. To boot he's got manga coloured hair! They don't rerelease important main characters besides Goku (sorry but arlia vegeta does NOT ****ing count, it was nothing but a proto design that barely anyone even wants to remember). They don't issue out enough versions of them in new form (well, with Gohan they're starting again... cheaply) and to boot they're paintapps are reverting back to manga style...
I feel like international dollars are now being spent catering products to the japanese market... I'm sorry but that feels wrong to me. Japan let the line die, fact, international sales revived it, fact and it's now their biggest line, fact. And now they're still catering to a demand that does not connect to the very market who supplied the profit that kept the line alive, even thriving? I'm sorry, I feel validated in not being disappointed by that.
