Well evidently there was a DS conference yesterday (in Japan I'm assuming...) where they announced a web browser for the DS! Yes, you read that right Opera will be making their browser available for the Nintendo DS. It will come on a DS cart not a firmware upgrade, and you can read more about it here.
Some of the other tidbits gathered were that Tetris DS will be a ***get title in Japan (1,000y=about $9.00) less than a normal Nintendo release. So hopefully when it's released here it may hit around $24.99, which I would definitely pick up. They also announced a May release date of the new Super Mario Bros. in Japan.
Yesterday, of course was Valentine's Day. If you connected to Nintendo WFC in Animal Crossing you got a letter from Nintendo containing a "Lovely Loveseat" part of the Lovely furniture collection. It wasn't anything rare or cool like the Coin we got a while back, but a nice touch. You also received a new bulletin Board entry from Nintendo in your town square.
