.220 build would be a nice addition. With all the talk of these tour files flying around, not sure if our builders are working hybrid for that. That would be awesome though....220 with 5.0 files and some tour files. The blackberry storm would be one hell of a machine and it would only get better from there.
I think if you look at the past you can see a pattern regarding leaks. Namely with the releases for OS 4.5 and previous new devices. For the most part when a device is new or an OS is new, there are many leaks. When a device or new OS has been officially released for a few months, leaks dry up. This to me says that the general public and the carrier are satisfied with the latest version and unless there's a security issue, it is unlikely to be updated.
