Yes.
A few of these sprites look like more than 2D but don't let it fool you. Capcom has a LONG track record of producing 2D art that kicks enough ass to appear 3D (semi automated) or even to appear to raise the visual limitations of a platform. Really the raw skill of dedicated artists churning out that work. Probably the same here. Tho frankly most of these did not fool me.
Just consider the amount of work you have to put in, if 2D is the best for that, and that if you want to learn and bring in 3D into your pipeline you have to trade in some artistic control for that efficiency.
BTW might want to link some of these images, long posts can be a bit annoying.
