A few things went unannounced during Nintendo’s GDC keynote this morning and the biggest news on the DSi front is the confirmation of 1000 free DSi points if you purchase the third generation DS within the first six months of launch. That’s quite a bit of free swag considering DSiWare games and apps will be divvied up into four price tiers: free, 200 points, 500 points and 800+ points. The DSi point to $ ratio is 100 to 1, so 1000 points is a considerable amount of free booty. So be sure to pick up your DSi between April 5th and October 5th if you want to cash in.
