According to unwiredview.  The Sony Ericsson Xperia X10 Mini and X10 Mini Pro will be released in France and Belgium starting late May (the Mini) and June (the Mini Pro).

Sony Ericsson has confirmed the prices of the two new Android smartphones: the Xperia X10 Mini costs €300 ($410), while the Xperia X10 Mini will be sold for €330 ($450) - both prices are for the unlocked versions.

I have a personal opinion towards Sony Ericsson, why is the Xperia X10 keeps on getting delayed?  First we heard, it's going to be release in Jan 2010, the March, then April.   Is it just me or Sony Ericsson needs to work hard in this super compeitive market to be more successful? Well, you don't have to agree with me.  Like I said, this is my personal opinion.
