ilomilo for XBLA right now?" Yes, there is -- or you could wait until it's "officially" released on the Xbox Marketplace come January 5 as part of the "Games for the Holidays" promotion. But really, who would do such a silly thing? (Either way, it'll set you back 800 Microsoft Points, or $10.)
Of course, since there's no way to secretly procure Ninja Bee's latest, A World of Keflings, or the puzzle/racer mash-up that is Raskulls from Halfbrick Studios, you will have to wait until their official launches on December 22 and 29, respectively, at 800 points ($10) each.
