The ride itself has been near completion for awhile now sans a few minor things , adding the AA's and etc etc..... the biggest delay has been Pixar Place as a whole.
There are now conducting interviews for castmembers that want to work at TSM this week. So they should start staffing it soon with CM's for some testing and training. I would give it another month, then there might be some unscheduled guest testing.
I don't think I can make it to WDW for the soft-openning of this ride. I'll probably need to catch this in the fall. Hopefully all the kinks will be worked out.
