If you mean Windows then i think there new one is out next year sometime, there is beta versions on the net but i have no clue how well they work. Check the link to read more about Vista, http://www.microsoft.com/windowsvista/default.mspx
i think it's gonna be release somewhere around next year remember this is make for 64bit base cpu so sorry for people who bought those Intel Centrino cpu which are like P3 also they recommended having about 1GB of rams. this is one up for the AMD since most of Intel's 64bit cpu sux.
