looks like a good mouse. not too sure what they did to it other than add some leds to it and a few hardware tweaks. http://steelseries.com/us/products/m...lseries-sensei i wanted to try the xai, maybe ill wait for this mouse to come out.

is there really that big of difference in optical vs laser mice when playing games?

(figured this mouse topic would go best in the sc2 section)
