Storyline or Studio 12?

Hi there

I have a question for you. Most of the eLearning I develop is used to train users on how to use software.

Currently I use Studio '09 and Captivate 3 to create my courses. It's high time I upgraded and of course I am loving Storyline but should I go for that or wait for Studio 12?

I'd be interested to hear from anyone who creates eLearning for software and is currently using Storyline. Do you like it more or are there features you prefer from Studio.

Much appreciated
