And the flood gates are now officially open. Just hours after Panasonic introduced its newest 3D Blu-ray recorders and players, along comes Sony to brag about its first 3D-ready standalone deck. The BDP-S470, which is slated to ship later this month for $200, arrives with the ability to handle BD, DVD, CD and even SACD, with a 3D Blu-ray upgrade (via firmware update) planned for this summer. You'll also find BD-Live support, BRAVIA Internet Video, a USB socket for playing back media stored elsewhere, 1080p DVD upscaling and TrueHD / DTS-HD Master Audio decoding. If you were planning to snag a BDP-S570 BD player or one of the BDV-E770W / BDV-E570 Blu-ray Disc home theater systems, you'll be elated to know that those systems will also get a gratis 3D update in just a few months, with exact pricing and release details tucked down there in the source. Time to pick up a pair of 3D Gunnar Optiks, don'tcha think?
