It would seem Razer have chosen the Leipzig Games Convention to launch their new mouse too, yesterday we got the Microsoft Sidewinder announcement and today we get the Razer Lachesis. Apparently the Lachesis Muta Muta is the largest pit viper in the world and follows Razers usual snake related naming scheme, it's latin name is 'Bringer of silent death' which is no doubt why the mousing device's web site is www.bringerofsilentdeath.com.

Considering it's pretty much twice as sensitive as any previous mouse, that's perhaps not a bad name.

There are plenty of image of the thing on the site but for the lazy it looks quite similar to a DeathAdder but with wider main buttons.
