1up.com has a new article online, mostly recapping what we already know, but there was a quote from Street Fighter 4's producer stating that they're planning on doing some minor tweaks.Details on new features for the home ports are still scant. Although Ono hinted that a full-featured training mode is in the works, he warned Famitsu to not expect massive changes from the arcade original: "Calling it 'Street Fighter 4.5' [as he did in previous interviews] was probably going too far.
We aren't making any major balance changes, but we do plan to rework some points which were plainly unnatural in the arcade version. It's more of a 4.1, you could say."
