GoPiGo or wait for the GoPiGo2?


I am really interested in getting this as a project that me and my son can do together. After reading through a few posts, I believe that the GoPiGo2 will be release very shortly. My question to anyone here is should I wait? There are not too many posts regarding the GPG2 and I would like to read up more on this… I have read in a different post that the GPG2 is easier to build, more durable, and a bit easier to use, but is that it? I was hoping that the tilting was fixed when using a RPi2.

Anyways, if anyone can provide me their opinions and recommendations I would greatly appreciate it. Thank you…
