Saw this in a couple places... and the news seems to be slow. Over at the Counter Strike page, they have news about right handed weapon models!. Anyway, read up:

Someone has contacted me and succesfully mirrored the CS weapon models!!! Yes, that's right folks.. Chances are very likely that you'll have right handed guns for CS BETA6.. I'm can't guarantee anything but things are looking for positive with regards to right handed guns. Don't thank me for them though, thank none other than Ben Wilder!! A true genious who figured out how to make Milkshape 3d mirror the bone structure and animations of the current guns!
