I can confirm that Season 5 finally started showing on Paramount in the uk yesterday on 28th Feb 2005.
Might not be important to the US, but that season (plus 6 and 7) haven't been shown in the uk for at least 5 years, because BBC held onto the rights yet didn't show them...
I never caught them first time around, so its like "WOOHOO", 3 new seasons of Seinfeld. And the quality ones too...
