A version of the Wii-exclusive prequel to the whole Dead Space story may be ported to PSN and XBLA if there's enough demand from users.
In a recent survey found by Kotaku, asked whether gamers would be interested in a "full HD interactive horror experience" in "guided first-person" - essentially an HD take on the unique Wii idea. A tentative price of $15 was also mentioned.
EA has yet to announce any plans to bring the spinoff to HD consoles, but with sales fairly weak on the Wii front it may be a move worth considering.
On a side note, the Dead Space love continues with confirmation that the sequel, Dead Space 2, is in development for handhelds. No platforms were mentioned, but a DS version is farily likely.
PS3/Xbox/PC owners - would you be interested in an HD version of Dead Space Extraction?
