If you care about pkmn, you've probably noticed the various hints to a G/S remake. I don't have time to talk about them all, so here's the official story on it from Bulbapedia (the largest/best pkmn wiki):
As announced by the official Japanese Pokémon Web site and TV Tokyo's TV program information on Friday, Pokémon Sunday is set to make a "world-exclusive first announcement" in its Pokémon Game Arena segment on May 10.
The most recent episode previewed the annnouncement, showing two balls, one gold and one silver, which will be opened to unveil the announcement's subject. Based on this as well as the fact that the game is said to have been the center of much speculation, many fans believe that the announcement will pertain to two titles: the Pokémon Gold and Silver remakes. It is also theorized that Junichi Masuda will appear on the show to make the announcement, since he did so both last month and the month prior in regard to other game-related scoops.
The next issue of CoroCoro, which will be released May 15, is likely to contain the announcement as well.
