Yeah, definitely a new team. I'm thinking Totodile, Pidgey, Mareep, Heracross, Larvitar...lol.
Yeah, Johto on the DS...sure is a pretty picture. There's been rumorus of a Gold and Silver DS remake with pretty convincing screenshots on YouTube but I don't believe them. They'll probably have contests, and the 4th gens will probably be available after getting the Johto dex or something. And I reckon the storyline could be altered slightly.
