If you've got some games that need to be registered, you have nine days to do so if you want to qualify for this year's rewards. 300 for Gold, 600 for Platinum. You need to do this fast if you need post-play survey coins, because they usually offer those a week after you register the game.
Last year, Gold got a calendar and Platinum got a choice between a floppy Mario hat or a mini version of Punch-Out!! for Wii. Japan usually gets better stuff, like a 2CD Super Mario Galaxy soundtrack and, I think, gold Wiimotes--though, I think those things are available all the time if you have the coins to spend. Our spendable items are fairly disappointing compared to those.
I managed to get exactly 600 coins registered in January, and I've been sitting on a bunch of other items since anything above 600 will be "erased" as far as next year's Platinum status goes. I think I have enough right now to have over 400 coins right off the bat for next time.
Crossing my fingers for a Galaxy 2 soundtrack. It'll be in vain, but it would be awesome. I was marveling at the Puzzle Plank music earlier.
