I hope it's not true about the Ratatouille ride being cancelled. Although it didn't necessarily appeal to me I think the resort needs a new ride for the 20th anniversary.
I agree with DisneylandParis, I'm not sure Star Tours 2 would really have much of an impact if that is the only "new" ride for 2012. Although the Star Wars films are being re-released would that ride alone make people who are from England, Germany, Italy who are on the fence about whether to visit sway their decision? DLP are probably waiting to see what impact ST2 has in WDW and DLR before making any decisions.
