Hi,
The 64 bit conversion has already begun. The first step of that is actually getting the Mac version of the UI framework ported from Carbon to Cocoa. This is what I'm mainly working on now, and I have to say it's going much better than I'd anticipated. There's bound to be something tricky which crops up though, there always is :-). Once that is complete I'll make the UI framework 64 bit safe on Mac and Windows, and then we'll get stuck into making TG2 64 bit safe. No timeframe at this stage, but the conversion to 64 bit is certainly underway.
Regards,
Jo
