ADOBE flash will NEVER happen. Reason - It's not open source and Adobe aren't gonna waste time porting flash to a platform not powerful enough. The flash player that was made was a port of an open source flash player, can't remember which one. But I think the best open source flash player at the moment is Gnash or something like that, so someone could theoretically port that, but I doubt the DS or DSi would be powerful enough to run it well. But adobe flash will NEVER happen. Unless done by adobe, but that is HIGHLY unlikely.
