I'm going to add my request / vote / plea for a version of Pythonista that embeds Python 3. I've been developing some scripts, on my Macbook, with Python 3 and I quite like the language improvements over Python 2. I'd love to be able to use those same language features on my iPad as well. My credit card is out and I'm ready to buy "Pythonista 3" whenever it hits the app store.
