Sony so often done that. They bring in a new technology that really is better than the rest and then back away and let it die. Real smart strategy there. They have done it with SACD and they did it with Betamax. Betamax was superior to VHS but Sony let it die and they haven't really supported SACD, releasing nothing now and not making their SACD disc hybrid, which opens up the market to more people to later explore the SACD side.
To be fair, I suspect SACD is partly a victim of being released prior to Hi-Res consciousness hitting the mass-market, and relatively few SACD pressing plants existing, and the fact that digital downloads are in the ascendency, this past few years. Altogether, then, it's been an uphill battle. I've never owned an SACD player, but I'd nonetheless be happy to see SACDs continue for a few years more.
Sony did make a wise move with Blu-ray - in fact, they stole victory from the jaws of defeat. HD-DVD was set to be the winner in that particular format war, because HD-DVD discs could be produced on very similar equipment to that already well-established for DVD production. However, the PS3 was a massively-established console that
included Blu-ray playback, so rather than half the world buying HD-DVD players, a massive number of gamers
already had Blu-ray playback in their homes, leaving a smaller number of non-gamers to purchase a dedicated player for new hi-def discs...and thus, Blu-ray won-out to become the default format, much to the chagrin of disc replicators around the world.
All in all, though, I find Sony a very peculiar company, this past few years. Very, very inconsistent at the top levels of the company.
