The DSi launch may seem like it was only yesterday but that hasn't stopped Nintendo from announcing a new version of its portable gaming system.

As we reported recently , the large-screen DSi - known as the DSi LL - will feature bigger displays (4.2 inch, to be exact) and a longer stylus. Because it's bigger, it will obviously weight more than the DS Lite and DSi, but the battery life should be improved.In addition to this, the Japanese version of the console - which will be launched on the 21st of November at 20,000 yen - will come pre-loaded with the DSiWare titles A Bit of Brain Training: Arts, A Bit of Brain Training: Science and Kiyou Akira Rakuhiku Language Easier.
While we welcome any new Nintendo hardware launch, we can't help but feel this move is something of a mistake; people that have just shelled out for the shiny new DSi - which, lest we forget, is an upgrade of a machine most Nintendo fans already own anyway - will be pretty angry right now. How many upgrades is too many upgrades?
