Yes, Konami ID’s are going away. Starting with the release of Pro Evolution Soccer 2010. What about games that already use the ID? Konami has no plans to patch old games.
Most popular game to use the Konami ID is Metal Gear Online. If your letting the Konami ID stop you from even trying the game. You are missing out. Good news if there is a Metal Gear Online 2 it should be Konami ID free.
