I don't think so. I don't have any information about it, but I just can't see it happening right now. With all the layoffs and budget cuts it's almost imposible to think any big makeovers. Except DCA, but that one was announced and agreed on in time.
I hope I can be proven wrong. :)
Why would you be disappointed? As long as they put the Pixar based attractions in Pixar Place. Would you prefer to have them all spread over Tomorrowland instead. I just hope they keep up with the trend concentrate all Pixar based rides in one area.
The Backlot Tour really has gone downhill...
