A new product listing for what is being called the "Microsoft Arc Touch Mouse" has prompted speculation that the software giant may be whipping up a rival to Apple's Magic Mouse. The device is listed with the product code RVF-00003 and has an MSRP of around $70 (the same as Apple's device), according to Long Zheng of istartedsomething. Zheng also notes that Microsoft registered the domain "arctouchmouse.com" in March, which is currently redirecting to Bing - a common practice for the company's placeholder sites.

You may recall a project from late 2009 that Microsoft was calling Mouse 2.0. As part of that research, the company was working on designs for a prototype multitouch mouse - one of which is pictured above. That specific unit featured a curved design similar to the existing Arc models, and it used FTIR to track multiple contact points. There's no telling if this is what's coming to market, but any new multitouch peripheral from Microsoft could bring some attention to development for native Windows touch applications, and we can't complain about that.
