But they have announced that all units will have wifi from now on. That announcement again came too late to make it into the original Tour. That's just my W.A.G., or theory, if you will.
The vairous RIM models use different hardware configurations. To keep OS sizes small, each device has it's own OS. You shouldn't see code for a bold chipset in a storm and vice versa. A unified OS to cover several models would be too large and wasteful like Windows installing legacy modem drivers an a brand new PC.
I do agree they should work on something fresh and new as far as OSs go. But I think they will stick to what they know, and just add features to the current OS style like a webkit browser we will see next year, complete with flash support. Wheather that will be too little too late, nobody knows.
