Hi Chris,
Thanks for the interest in NGUI Infinite Pickers.
I've already got an NGUI 3 version ready - no problems there.
What I'm planning to do is release an NGUI 3.0 only version on the asset store, and keep a NGUI 2.7 version at the disposal of customers, should they need it. I feel that NGUI 3.0 is an important step towards the new Unity GUI, and would like to encourage users to upgrade as well as to maintain a clean, not too "if"fy code base.
Don't hesitate to ask questions if you have any! The unity forum thread is the preferred means of communication, but I'm happy to reply here or directly if needed.
Happy picking,
Gregzo
