Chun Li may be cute but a Chun Li Sackboy is downright irresistible, which would explain why Sony appears ready to give some of the Street Fighter gang a LittleBigPlanet makeover in the leadup to the release of Street Fighter IV.
Images of Sackboy renditions of Chun Li, Guile, Zangief and Ryu were initially dug up by Spanish PlayStation forum PSNow!, but Eurogamer says they were later pulled "as requested by Sony Computer Entertainment Europe." Fortunately, take-backs aren't so easy on the internet, and the images had already been picked up and mirrored by the gang at Ripten, where they remain.
It's quite possible these images are the work of a talented fan, but as 1Up noted, Capcom promised a "'Little' Street Fighter surprise" for the PlayStation Network in the "Season of Street Fighter" press release in mid-November. Neither Sony nor Capcom have commented on the images.
