Mostly on the Facebook pages with those wanting Majin Vegeta, Nappa, or God Goku. I may not even fully understand the limitations but I believe 1.) they don't produce anywhere near the amount of web exclusives and 2.) it will, more than likely, always be an anime repaint of a previous figure.
Were they the limitations you were thinking of or are they something different?
You're right on those points.
I'm just more disappointed in the fact that people want a prominent character in a prominent depiction as a SDCC Exclusive. I'm not against a potential Goku figure as a SDCC exclusive, but I don't think it should be an anime or manga repaint because those are THE main depiction of that character in that medium. Couple it with SDCC, where quantities are limited and given Bluefin's practices lately (lifting exclusive limits) and the SDCC Exclusives get snatched up quickly by scalpers and resold at higher prices.
I'd much rather see those odd repaints that your collection can "do without", much like Arlia Vegeta or Kaioken Goku. Look at how anime SDCC SSJ Goku is in the $500 range. Insane and that's THE anime depiction of SSJ Goku.
Unfortunately, the one good point you bring up is that Tamashii's track record does lean towards anime repaints. I hope that doesn't turn to be the case this year unless it's something unique...
