The PS4 might not be backwards compatible…at least, now how we expect.
According to sources familiar with Sony's plans, the Wall Street Journal reports that the PlayStation 4 will be able to stream PS3 games over the Internet. This streaming service will also play new games stored on optical discs.
This is just one PS4 feature among others that is specifically designed to "bolster its position in the market," although they didn't go into further detail. However, you may recall that last year, Sony acquired streaming company Gaikai last year for $380 million and since that time, the Gaikai website has teased images from the Uncharted and Killzone franchises. Lastly, Sony has updated their PlayStation Meeting 2013 website to include a video called "PlayStation Evolution," so everyone's gettin' excited. It seems like the PS4 unveiling is only a few days away!
It'll be very interesting to see how people respond to the announcement.
