Capcom offered the first look at Rockman Zero Collectionwith a new trailer on the game's website. Well, second look if you count the original games as the first look. Unsurprisingly, the collection as presented on the DS looks just like the games running on GBA, with some placeholder imagery on the bottom screen.
Most of the time, it appears to be character art of Zero or the current boss, but the trailer also shows a menu of what looks like an artwork collection. So you can play games, and look at pictures from those games! Basically, if this is localized, buy it because you want copies of these games, not for any new content, though some might still show up.
