Well, I don't want to be that guy who starts spouting hybrid theories, but if Sasakibe meant that they can USE bankai, then that sort of fits into my theory: the Vandenreich are a bunch of hybrids. Quincies/Hollows/Shinigami? I don't think this theory is that outlandish: based on what we've seen throughout the series, hybridization has been a huge theme. Ichigo was one. The Arrancar and Vizards are. The Fullbringers are. And now, Ichigo is one again. Now we have seemingly Arrancar-masked Quincies able to possibly use Bankai... I don't know if it's true or not, but it's possible.
