According to this interview, Sony Ericsson came back on its decision of not shipping any news updates for the Xperia X10 and will prepare an update to Android 4.3.3 (aka Gingerbread).

Is this really due to the deep disappointment the previous announce caused, or just an opportunistic move from Sony Ericsson as the Xperia Play device has a lot of success?

Anyway, I might reconsider my decision of not buying Sony Ericsson products, but this will more be a matter of a good opportunity than any kind of loyalty towards them.
