Ehh...aside from having a Sonic Boom, the new Charlie doesn't seem to be all that similar to Guile anymore. His Flashkick functions differently, his command grab, his teleports, his normals. It's all different. And it's a pretty safe bet that he's a command character on top of all that.

It seems to be similar to Ryu and Gouken. Their fighting styles have some thematic similarities, but that's about it.
