I was at MK on Tue., 5/15 and took a good look at the progress being made. I saw workers painting as well as many of them doing work on the queue. There were also workers laying down what appeared to be electrical wiring around some of the tracks. In the evening there were trains running (albeit without any guests). However, as was noticed while riding the WDW Railroad, all of the animatronics had been taken out of the "town scene" (presumably for refurbishment/ repair). All that being said, I doubt there is going to be a soft opening in the next week or two.
As an aside, I was really hoping the Liberty Belle refurbishment would have been completed a few days earlier than the scheduled 5/20 completion and my family and I could have ridden it, but alas, no luck .. just another excuse to visit next year I guess!
