According to PalmInfoCenter, the PEG-UX50 started shipping in limited quantities. A quick trip to SonyStyle Europe shows that it costs 1.005,91 EUR (incl. VAT, of course, but VAT doesn't quite cover the difference from US$699...) plus shipping charges.
The shop is rather badly designed in that it won't show shipping charges unless you actually buy something, so I have no idea what those would be. Furthermore, the PEG-UX50 is listed as being "on order" (i.e., not in stock).

Like... You gotta be kidding, right, Sony? Why should I pay a premium for being Portuguese?
