Well it always hovers around 15-20 minutes on both Green and Orange, so yeah. Occasionally Orange will get up to about 45 or so, maybe 60 on a day like NYE, but it's very rare to wait long for M:S. The longest waiting you do is going through the pre-show rooms.
And ironically Body Wars was a 4 hour wait on NYE the year M:S before opened, with the same exact capacity as M:S.
