Yup it will take some further time till a win version will be available, but it will come. Just to make a few things clear, the iphone support isn't available yet, it has only been announced and whilst the Wii support is available this is a special deal were you need a) a Nintendo devkit and b) a special $ intensive licence, so for the normal indie at this point it leaves the target platforms win (xp,vista), osx (ppc,x86) standalone (executable), webplayer (IE, Firefox, Safari), widget (useless imo) market for the pro version and osx standalone, webplayer (watermark on win) and widget for indie.
If you're serious about the development of a 3d game/content then it's worth the investment of a mac and the licence. If not then i would rather wait for the win version to arrive unless you want to swap to a mac nonetheless.
