Heh, the new games should definately be interesting, though the sources I found said that it would be Pokemon Platinum instead of Pearl. However, Pearl does sound more reasonable for a good match to Diamond. Platinum would probably be a good name for the fifth generation (if there is going to be a fifth generation
). Anyways, I can't wait to see the new Pokemon and movesets that await us in the new games to come. With all the new DS features, there's sure to be much more interactive fun with the new generation of Pokemon than with the last.
Also, I found that Pokemon Dash is supposed to be compatible with GBA title Pokemon Emerald, though in what way I haven't yet found.
