Just to put my viewpoint in here, although it may bother lots of the fans here about what Paramount did (and looking at it it really is scummy), what you have to think about is that the casual buyer is looking for the movie first and foremost. They may really not care at all about bonus features (when I get other movies, I'm really not that concerned about the bonus features at all - if there are some, good. If not, no big deal).
As far as IMAX formatting, I don't get why that's important when you're viewing it at home. Yes, there may be more clarity, but it would be like looking at a letterbox VHS movie on a 13 inch TV, unless you have an IMAX screen handy.
