Nintendo of America has just tweeted images of two new Nintendo DSi color options, matte red and matte blue. According to the tweet, the pair will go on sale "as early as this week." There's been no mention of pricing just yet, but it seems likely that the new models will be priced in line with other color options. The DSi recently saw a huge price cut from $149.99 to $99.99, while its larger sibling the DSi XL was reduced from $169.99 to $129.99.
