People keeping up with the new info should already know about the stuff on it. You can go to Kanto, Kyogre in Gold and Groudon in Silver (Definitely... getting Gold), get both to fight Raq, the new artwork for the characters, etc.
They made a place to re-fight the gym leaders, which was a good thing, but this time, I wish they also make it available to fight Team Rocket (grunt, admin, boss) afterwards. It is a shame we couldn't hear Team Galaxy's theme after beating the game, after all...
By the way, love this picture:
