For anyone who hasn't experienced the WDW version - it's a 1.0 iteration. From day one, DLR's was a significant improvement - a lot of this update is just getting it to our level. The quality of the ride at WDW was almost something closer to something at Six Flags or Cedar Fair (or even the Lego version at some malls) - something that became comparatively embarrassing after a while. "The Magic Kingdom is a kids park" - so it was okay if it was meh.
It wouldn't surprise me if they bring this update to DLR, but I don't know that there's as much as an imperative as there is at WDW. WDW's has desperately needed this for a long, long time.
I couldn't agree with you more.
WDW's version is an embarrassment and needed this 10 years ago.
