More chance of buying

Which one would there be more chance of buying? (And you could only pick one as well):

Diablo 3

or

Fallout 3

Personally F3, even though i rarely play 1&2 of both

Well considering that Fallout 3 will be out before Diablo 3, the Chance of buying Fallout is greater at the moment, since there isnt a Diablo 3 release date.

Id buy both anyhow :)
