While I agree with your statement, there is one exception I believe to be the case where WDI (more specifically Tony Baxter) has hired one of their Next Gen Imagineers/Baxters. And that is Michel Den Dulk (whom Tony referenced to in his letter and is a Tony Protege). I know he was given a modest project with Fantasy Faire, but I've seen some of his concept art he drew out to go along with the projects he was involved with when working for Efteling Park and Europa Park. After seeing them and hearing Eddie give him a vote of confidence, I think the sky's the limit for this guy. I truly believe that if he's given the proper time, resources, budget to complete a project assigned to him, he can do great things. I know one isn't much, but at least it's something.
Speaking of the transition of WDI, I keep this phrase in the back of my mind "Out with the old and in with the new". While you as a company are always striving to find the next gen or latest and greatest employees, you need to keep the oldies around to show them how to get things done the Disney way. I'll use the animation studios as an example if that's okay with you (since that's my favorite unit of the company). Back in the 70's when the nine old men were really non existant anymore, Eric Larson/Ollie Johnston/Frank Thomas knew and understood that in order for this animation studio to succeed in the long run, they had to persuade to management (at the time) that a hiring draft needed to occur in order for new animators and ideas could be brought forth to the table. Those 3 old men stook around and mentored/taught those new animators like Glen Keane and Andreas Deja about what it took to create a Disney Animated Film and draw an Disney animated character to perfection. It's that kind of mentoring/crowning of sorts I'd wish WDI would let Tony perform with folks like Michel (esp. when Tony wants to do it considering that he understands so after learning from Coats and others).
Anyhow, back to NG now.
