You really don't expect features for free post-release, right?
It's really good to know two things:
1) We won't see feature additions via firmware to any other models in the future, and
2) We have a someone who knows exactly what Canon will or will not do in the future, either through direct insider knowledge or by virtue of being a professional, perfectly precise prognosticator.
FWIW, there have been other examples of adding features/functionality via firmware in the past...direct joystick access to select AF points was added to the 1DIII and 1DsIII, SDHC support was added to the 1DsII, to name a couple. So, if you don't mind, I'm still going to keep on hoping that they add a user-selectable maximum for Auto ISO to the 7D...
