Sources at the studio tell TMZ ... their tour has been put on ice since the hacker attack ... and a big reason is that it's 2 hour walking could pose a big threat to Sony. The tour is touted as a behind the scenes look at a working studio. The idea of someone straying from the group is too real a possibility.
We're told the tour will not resume until sometime after the first of the year, but no date has been set.
