im would be more concerned with the controls for BW2. It still looks clunky and slow compared to MP3, even on beginner settings. I would seriously get it if controls were revamped for this game.
As for the marketing, yea I still don't get why nintendo doesn't try to expand the fan base for their games. There making tons of moolah yet they don't seem interested in selling their games. I still feel bad for Retro Studios pouring their heart into MP3, and not being able to sell over 1m because of a lack in marketing.
