Should i choose 2.x or 3.x - Confused

I am planning to use CodeIgniter. I m confused which version to use.
Obviously 2.x is the stable version to use right now.

If 3.x is released, What should i do?
Can someone clarify my doubts?

I think codeigniter 2+ good because compatible with hmvc if need to use hmvc codeigniter 3 does not work with HMVC

There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
