Here at Dealspwn we strongly OBJECT to the fact that there's been no localisation announced for one of the finest puzzle-solving mashups we could possibly imagine (Batman vs. Holmes? Cole Phelps vs. George Stobbart?), especially considering that Japan will get Professor Layton vs. Ace Attorney pretty soon on November 29th.
Until we do hear news, we'll just have to watch this TGS trailer, sigh loudly, and hope that someone at Capcom overhears.
