Let's hope the graphics will be sprite based with pixels and low-res. I can't stand the flash graphics as seen in the concept artwork. I couldn't also stand the irritating Flash/sprite mix of CV Harmony of Despair.
Edit: And no, please no polygons as seen in Mighty No. 9. Both flash and polygons should be forbidden in 2D games. Even the Scott Pilgrim game had sprites, including subtle tit animations. This is how modern sprite work looks like. Google for Paul Robertson, if you dare.
