Kevin Rose jumped on Facebook video (login to Facebook required) to basically confirm what he said previously about copy and paste, saying it would be across apps, with cut available as well in those apps that support it (?).
He also confirmed hearing MMS would be enabled from multiple sources, something he said he didn't know previously.
A third, unidentified rumor was mentioned but not elaborated on as Rose said he had conflicting sources.
That was it from Rose, though hopefully not from Apple. Just over 12 hours from now we'll find out for sure!
