I think I will wait.

I couldn't quickly find if you still need a Mac to develop iOS and OSX? My guess is yes. That requirement was buggy and a pain in the arse with XE2. I remain unconvinced that Embarcadero know what they are doing.

Personally I have gone cold on Delphi. I felt extremely let down by XE2. A complete waste of money and no support. I am now switching my company's development away from Delphi and will instead be mixing it up using Smart Mobile Studio and Contruct 2. HTML 5 development is a perfect fit for what we do.
