Capcom has just announced Street Fighter IV for iPhone, and it should be coming to the iPhone this March! IGN has the details:

Capcom is not accepting any loss of the console game's beloved art direction in the iPhone edition. It has taken assets straight from the current-gen code, so the new art style that won universal accolades is faithfully recreated on the iPhone's smaller, but crisp screen. In our shots of Ken and Ryu battling it out, you can see the fidelity to the console version at play. These are the same models, just slightly scaled down – but with minimal loss of detail or color.

My childhood reborn. I want. Let us know what you think!
