I think it would lead to faster bug fixes as long as Autodesk's competitors also switch to this model since it would be easier to switch to a competitor.
my 2c: what happens with my data when the lease time ended? I can't open my data anymore. That might work better with AutoCAD based software as I can use DwgTrueView for opening and plotting DWG's, but what's with Revit, what's with 3DS-Max files?
It's a step to "I'm not any more owner of my data".
Next issue might raise if I want to use my data a year or two later ... I will then have to lease the next release (or whatever release is current then). Again, that might not be a problem for all as upgrading of data work's ok with 3DS-Max, but e.g. for Civil3D or looking to texture-mapping issues when upgrading from AutoCAD 2010 to 2012 or 2013 ... Then you have to work hours for getting the project back to live before you can start your work.
So if I would think about leasing I would verify that I can lease an old version years later too.
Just thoughts ...

Sounds good but not really. What if you let the lease lapse and a day after it lapses you actually need to open the document you just created? Annual subscription makes more sense because the long term costs are lower. (versus $199 for a 90 day lease for a single product).
