I think price is going to doom the Xperia to insignificance. Without MAJOR subsidies to price that a carrier would offer, there simply aren't enough SE fanboys willing to spend $1000. Plus, SE's record with firmware isn't so good. As a T-Mobile user the Xperia looks intriguing because of the inclusion of AWS (TMO 3G), but is it worth the price? Probably not. Nokia can completely blow away the Xperia for TMO customers by releasing the E71 version that is to include AWS.

The iPhone is, well, the iPhone. Sales will keep rolling along for some time. Look how long the iPod has been hot, only recently showing a flattening out of sales numbers. Apple is the Donald Trump of the electronics world. Self-promotion is their/his strong suit.

The BB 9000 will sell well too, as almost all new BB models have. But the 9000 is a major leap technologically, which will win converts from other platforms. RIM has found a superior balance of enterprise features and consumer features, and has also struck a very Apple-like balance of form and function. Gone are the days when Blackberrys worked superbly but looked like ass. These things are beautiful to use, beautiful to look at, and beautiful to hold.
