With the economy, I think these kinds of advanced features will be put on hold. Here are my predicitioins:
1) PRICE WARS!!!! Crappy economy + increased competition = lower monthly bills
-focus on upgrading networks for upcoming increase in smartphones
-improved battery life
-tethering
-less focus on fancy features, i.e. video calling, holograms, etc.
-iPhone will still dominate despite Palm Pre, Android, etc.
-dark horse prediction... iPhone on other carriers
