It's tough to redo a relatively modern line without it. All the updates to older properties are one thing, and the G1ification of Prime and Animated is doing something different.

Throw in today's smaller budgets and they've removed the one thing they really need if they want to improve on what we've had before - the cash to really up the parts count and engineer them all out.
