What's Going to Be the Next Handset from the XPERIA Line?

I think you'd agree that, for today, the most awaited phone from the the announced phones from Sony Ericsson is recently announced XPERIA branded smartphone Sony Ericsson X1. This device is the first truly high-end phone and combines almost everything what we might expect and need from a device of this class. But do you know what is more interesting than this phone alone? It is the XPERIA class, because as Sony Ericsson promises, all XPERIA branded handsets will be high-end smartphones and the X1 is only the beginning.

But what kind of smartphones will present to us XPERIA class? As we already know, Sony Ericsson X1 is a Windows Mobile loaded smartphone and many of us thought that XPERIA would be Windows Mobile based smartphones class. I mean, one time I really thought that the XPERIA class was a new line-up of the Windows Mobile smartphones (I don't know why, but I really did). But no. It looks like that, I and many other people were wrong and the reason of this is a French article which contains interview with Pierre Perron, CEO of Sony Ericsson France.

There is one interesting question in this article (I've translated it via online translation service, so sorry if there are some mistakes :D):

Mobifrance: XPERIA X1 is Windows Mobile loaded smartphone. Will all models of this range work with this operating system?

(Original: Xperia X1 embarque Windows Mobile. Est-ce que tous les modèles de cette gamme fonctionneront avec ce système d’exploitation ?)

Pierre Perron: No, Not only Windows Mobile, we work with all operating systems. We even have significant shares in the UIQ platform. However, with Xperia, we will address the users “Experiencers”. These demanding customers which wish all technology and the innovations in their handsets without compromise. The range Xperia will be enriched with other smartphones running Windows Mobile or Symbian or UIQ or others who will complement this range.

(Original: Pas uniquement, nous travaillons avec tous les systèmes d’exploitation. Nous avons même des parts importantes dans la plateforme UIQ. Toutefois, avec Xperia, nous adresserons les utilisateurs «Experiencers». Cette clientèle exigeante qui souhaite toute la technologie et les innovations dans leur terminal mobile sans compromis. La gamme Xperia sera donc enrichie d’autres smartphones sous Windows Mobile ou Symbian ou UIQ ou autres qui viendront compléter cette gamme.)

I don't know how about you, but for me it's great news. I really like Symbian UIQ platform and it would be great if the next phone from the Xperia range will be based on Symbian UIQ. Just imagine Symbian UIQ running on a handset like X1. It would be great, wouldn't it?

So the answer to the question: What's going to be next handset from XPERIA range? Looks like it can be anything, not only Windows Mobile loaded smartphones...
