The two Brain Training titles will be first games released on the US Version of the DSi Shop, Nintendo of America has confirmed.

However, the games will be "retooled" for the new system, according to NoA president Reggie Fils-Aime.

Nintendo UK on the other hand has said that it is too early to comment on what we can expect from the DSiWare line-up for Europe.

It is thought as well that when you do buy and download games from the DSiWare Shop onto SD card (via the new SD card slot), you'll be able to download them for free again if you delete them. That's how Wii operates with the Virtual Console and WiiWare, so fingers crossed we'll see the same function for the DSi.
