Well, that didn't take long. Just two days after Japan's Nikkei newspaper reported that Nintendo was planning a new variant of the DSi sporting larger 4" screens (which it called "speculation"), the Big N has gone and announced it -- for Japan, at least. Called the Nintendo DSi LL, the hefty handheld will be released in Japan on November 21 for a price of ¥20,000 ($221).
