Last time I checked, the anglerfish was in neither DP or Platinum's dexes. According to my guide book it can only be found in Route 220 with a Super rod. Accordingly, you can only get a Super rod in Platinum via post game. This means that they are actually going to do more than just the 210 provided mons from Platinum, or they just made it that you can get the Super rod earlier.
Thoughts, and anyone want me to make a separate discussion regarding it?
