VG247 is reporting that a DS version of Assassin's Creed 2 will be released with the other platform versions on Nov. 20. Amazon's got a product page up about it, too.
Ordinarily, retailers listing a game with an unconfirmed platform version shouldn't rate much attention. It could be mis-entered into a system somewhere. But VG247 was adamant that something called "Assassins Creed II: Discovery" would hit for the Nintendo handheld. Ubisoft would neither confirm nor deny it to them on Thursday.
We've reached out to Ubi PR either to smash the rumour or get the same response VG247 received, which is none. If anything comes through I'll update it here.
