I can see a possible RAM upgrade and even the keyboard, but I don't think Nokia is going to risk killing off the current device for a completely overhauled device that creates the ultimate Internet Tablet. I also think VoIP and even a browser and pluggins upgrade will fix a lot of the major issues with the software side of the device. I just don't see enough of a argument for much change in the hardware, and If I know companies like Nokia, they won't either.

Of course, knowing how quick Nokia is at putting out new phones, this new Internet Tablet market they seem to have created may see similarly quick device rollouts. Heck, even large companies are "creatures of habit".
