Capcom has labelled the move to offer the upcoming Resident Evil 6 demo exclusively on Xbox 360 for a two month period as "a strategic business decision".
The firm offered no further comment when contacted on the matter by Boxden.
Capcom announced earlier this week that action game Dragon's Dogma will offer access to a playable demo of Resident Evil 6, with all retail versions of the May release set to include a code to download the taster at a later date.
"Purchasers of the Xbox 360 version of Dragon's Dogma will be able to redeem this token and download the Resident Evil 6 demo globally on the Xbox Live Marketplace for Xbox 360 60 days earlier than any other platform starting on July 3," the publisher said.
Those with the PS3 version of Dragon's Dogma will be able to play the demo from September 4 in North America and Japan and September 5 in Europe.
