If only! Trying to get any information out of Sony about anything, let alone actual review samples, is a perpetual nightmare. Yes, we've spoken to their PR people, yes, we've explained our readers/web users might actually like to know what Sony's up to, but so far our pleas have fallen on deaf ears.
However, Mr (magazine) Editor Melville and I are due to pay a visit to Sony HQ shortly, so your request (and those of many others) will be raised with the powers-that-be.
