Japan has a 5000 points card too - Will we see this elsewhere as well?

If you ever find yourself wanting a little bit less or a little bit more than 2000 points worth of games, say, 1000 or 3000 points, and you don't have a credit card, then worry no more - 1000 and 3000 Nintendo Points cards will be available in shops next month on the same day as the DSi (April 2nd in Australia, 3rd in Europe, 5th in the US).
