Nintendo has unveiled the next iteration of the DS at a press conference in Tokyo.

The DSi, as it's called, will have 3.25-inch screens - that's 17 per cent bigger than the current model. It will also feature a 3-megapixel camera.

You'll be able to take pictures with the DSi, save them to SD card and view them on your TV via the Wii. The GBA cartridge slot is being done away with.

The DSi will have a built-in browser, and you'll be able to download games - known as DSiWare - and store them on the SD. Some titles will be free, while others will cost either 200, 500 or 800 Nintendo points (GBP 1.70 / 4.25 / 6.80). There will be a special deal offering customers 1000 points which must be spent before March 2010 - but it's not clear yet what the terms are, or whether the deal will be available in Europe.

A separate DSi Shop selling downloadable software is also being launched. Customers will receive 1000 free points to spend at the shop

The handheld's audio capabilities have been improved - you can now adjust the pitch and playback of sound. This is designed to help with language study and improve the experience of listening to music, apparently.

Today marks the long awaited arrival of “TU2” for Halo 3. Despite plenty of rumors to the contrary, this update is not ushering in a new “BR spread,” nor does it incorporate enemy AI and campaign components to the Forge map editor. However, beyond the behind-the-scenes technical implications, there are two major components for fans to note.
