Sony Europe today announced its intention to release 3D Blu-ray Disc players over here, though it was silent on two crucial details: when and how much they will cost.

Sony took the wraps off the BDP-S470 at last month's Consumer Electronics Show (CES) and today added the BDP-S570 to the line-up. They'll go on sale in the US this month for $200 and $250, respectively. That's the equivalent of £129 and £161 here - but tax and so on will inevitably mean we pay more than that.

Sony's BDP-S470: like the BDP-S570, no 3D playback out of the box

The two players have plenty in common: in addition to 3D, they do BD Live, DLNA, 1080p playback and all the usual Blu-ray audio options.

The S570 has some key features absent from the S470: Wi-Fi on board, 1GB of storage and Sony's noise reduction tech designed to make internet-sourced video look better than its resolution would suggest.

We mention DLNA and 3D, but Sony confessed that both will not be available immediately, the two technologies requiring firmware updates in due course. So 3D support won't arrive until the summer, it said.

That's no problem, of course, because there aren't any 3D BDs you can buy yet - and not many tellies, either - but it seems a bit lame to have left out the Windows 7-friendly DLNA for the time being.

Riding the iPhone wave, both devices can be remotely controlled by iPhone app, BD Remote, which Sony has now make available on the Apple App Store. Be warned, it only gets one-and-a-half stars out of five. ®
