It looks pretty much "dead". I don't think there will ever be a re-incarnation of Codewarrior for Windows.
My suggestion to you is:
Do as I do. Keep the Codewarrior Box in a VERY safe place, and Codewarrior installed on your HardDrive. Lite up some candles each year, pull over your Blood Sweat 'n' Code Shirt then open a bottle of J.Walker and drink, drink, drink.
Codewarrior is a Legend - something like the Holly Grail for coders you might say.
For all of you who didn't have the chance to see Codewarrior blooming on their HardDrives ... well, sorry but's a tough one.
Long Life to C++
