That didn't take long. The video after the break shows an infinite combo loop in Street Fighter IV.
It only works with Fei Long against either Seth or Abel, apparently.
Capcom's told Destructoid that the upcoming Championship patch may fix it. Other loops are also being rumoured.
“We’re always looking into the possibilities with the Championship Expansion Pack on the horizons," said a PR chap.
"But we can’t confirm anything at the moment yet.”
