No, this isn't a rumor about a game in the works. It's another, "Boy, wouldn't it be nice if someone did this," post.
First, to explain Shufflepuck - it's kind of a cross between pong (you use paddles) and air hockey (you have to whack the puck to get it moving fast). The game had a lot of personality, but was a little simple - 1p versus computer only. A DS remake can take full advantage of the touch screen to control the paddle, for starters, showing your opponent on the upper screen. Multi-player and online are a must, I think. The DS could also allow for some interesting customization - let players customize the design on their paddles and their avatar.
This may not be enough to sell as a game itself, to be honest. It may need to be part of a many games cart or an unlock-able.
It would definitely be fun, though.
