Here is my cents worth of an opinion...
It would make sense that Spectro is being updated during its hiatus from WDW, but I thought I read somewhere that is was moved to another park(other than DL). But it would make sense that it will return in 2011 or 2012 IF its being updated with LED's...it will take awhile for all the parade elements to be torn apart and updated. Which brings me to another topic that has been around the block forever...
If they can update, not only a parade or attraction, WHY CAN'T THEY UPDATE LIGHTS OF WINTER WITH LED's and bring them back to add to Epcot's Holidays? From the videos I have seen without the colorful arches, the area looks boring! But enough said, only time will tell! Maybe we'll be surprised in 2011 or 2012!?!?
