I certainly understand the desire for this type of ride. It looks REALLY mild to me though and just sort of neat not really showstopping at all. I think there are some attractions worthy of being cloned around the world but I'm not sure that the minetrain coaster is really one of them. I'm certainly growing tired of the recent trend of nearly identical clones being dropped into parks lately. Mild differences in queue is just not enough for me.
If something goes into the theater spot or the motorboat cruise I don't NEED it to replicate a ride system that just happens to be in recent memory. I'm just as happy to see a ride that uses the Pooh ride system from TDL or maybe something totally new. Maybe a ride that's like Peter Pan but lasts longer?
I know its popular to ask for WDW's new ride, I just don't really see a reason to beg for it other then its something that sits in all of our recent memory. If they do clone it I hope they take time and do it like how they used to do rides like Splash Mountain and make the next version different and improved.
