Capcom quickly shot down the rumours of an Xbox version of Resident Evil 4 being in development, through trusty C&VG. C&VG quote Capcom as saying:

"At present we are focusing on completing the Gamecube version and beginning development on the PS2 version. Whether Resident Evil 4 will appear on other platforms has not yet been determined."

From the quote above, it is still unclear whether or not an Xbox version will be available. However, with Capcom’s small quantity of games on the Xbox, it may, in fact, be the truth. RP
