I was in WDW last week. We avoided DHS like the plague for the first SWW, so we didn't get there until this past Monday. We were at the park for opening, fairly close to the front of the "line" for rope drop, and by the time we "walked" to TSMM and got our fastpass (I was one of the first in line for it) and then jumped in line, the line was already marked at 50 minute wait....it ended up being about 25 minutes, but that's still at 9:10am! As far as Star Tours, right after we rode TSMM, I went right over there to get a fastpass, and it was a 10 minute wait for the attraction....
Each time we walked past Star Tours it was never more than a 25 minute wait, whereas TSMM hit 120 minutes that day. So I'd say no, Star Tours isn't helping! (Although, the new ride is AMAZING-- and I'm not even a huge Star Wars fan!)
