Well put cholo.
Right after my last post on this thread the whole website and 2k trademark thing popped up, so I was like 'doh!'.
But then we found out that the trademark was a year old and I read what Jim said on the DVinfo.net thread recently, which continue to fuel the 4k speculation within me. But, who knows for sure, eh?
Either way, I look forward to NAB and wish (for my lack of patience) that it was in March and not April.
