Sony president of Worldwide Studios apologizes for not showing hardware last night during reveal.

NEW YORK CITY--Notably absent from Sony's PlayStation 4 announcement last night was the hardware itself. During a roundtable discussion today, Sony president of Worldwide Studios Shuhei Yoshida apologized to gamers for not showing the device itself.

"I'm sorry we did not show the hardware," Yoshida said. "But we have plans from now--in February--through the year for the launch. We like to disclose things based on what we think we really want to communicate first. And next time we will talk about these things."

If Sony had shown off a PS4 unit last night, it would not have been representative of the final design. Yoshida was asked, "Is the final hardware finished?" To which he bluntly responded, "No, it's not."
