I expect bug fixes. Maybe some minor functionality holes partly patched.

I have had lots of firmware upgrades on lots of hardware devices, and they rarely bring a lot of new functionality.

I most certainly do not expect them to come* with a new version of Ovi Maps. I honestly can't see any reason to believe they'd convert an old version of Ovi Maps into something that would work on Maemo, just to have it replaced a month or two later.

* as a firmware patch. I fully expect at some time there will be a full gps solution - as payware.
