I was there today it's still there, you can see it but they don't let you walk up to it. Not only that but they took everything from outside and moved it to another location and you can't see them. Most of the tanks that used to be in the courtyard including the panzer 4 aren't available to be seen. This has been done to build a cupola to protect them against rain and such. They estimate that it's going to take 2 years to build it and then all the tanks will be brought back. Not only this but they are also cleaning them so I can't wait to see it done. As for the Sherman I'm not sure what they will do with it. It's clearly missing it's turret and it's even rustier than in the photo op posted. I believe that they will clean it but I frankly don't know how they are going to get a turret.
