Well, making them into 3DS games would take too long, wouldn't it? Sure they already have everything done but making it into soley a 3DS game would require them to..well...remake them (more than likely). That could take too long. I'd prefer if black and white are played on the 3DS or DSi they will have upgraded features. That way the people who don't have a DSi or 3DS aren't left in the dust, and all of us w/ a 3DS or DSi will be happy.
