Their latest update email says Q2 for Epic HACKS wave 1 as well as Hellboy wave 1, which is weird considering how far apart the pre-orders for those were. I expect the HACKS will come out within the next 4 months but Hellboy might be pushed back. The last thing they showed of the 6" wave 1 were unpainted test shots in June last year.
With the greedy dickhead in charge of Boss Fight I think it's always a good idea to wait to see the final product before ordering as you never know when he'll attempt a rug-pull, but with that said I think the degradation of quality with the 3 3/4" figures is because he has no interest in that line and is just slowly killing it off while milking whatever he can out of it. I'm expecting the 6" figures to continue to be the quality of Red Sonja, for the near future anyway.
