To be perfectly honest nobody really knows what might happen in 10 years. Regarding the Internet, 5 year predictions are long time predictions. Nobody really dares predicting Internet technologies beyond that.
The 2020 Workshop (WS6) barely touched the subject and didn't get much past the intellectual property or RFID but these are not important for way the Internet will look 10 years from now.
What we can do to get an idea about the Internet of the future is to take the current trends, extend it into the future and also keep in mind that this predictions are not taking into account the developments that will most certainly accelerate the prediction. That means that the predictions based on the current trends are the worst case scenario.
What would such a prediction tell us? We now have ~1.7 billion Internet users (~25% of world populations) and because the Internet is predicted to double every 5.32 years by 2020 everyone might have Internet access. They might not have electricity and clean drinking water but they will probably have solar powered personal Internet devices provided for free by the wireless Internet companies to assure they have a higher market share (Romania already experienced this when the biggest ISP in the country gave away for free 3G mobile terminals to all their clients).
What will the world look like when everybody has mobile Internet access? How will the 2020 services look like? Nobody know but one thing is sure. The IG needs to concentrate on the real issues of the Internet growth and let the public sector work out it's own problems (like IP and RFID).
