Release dates for upcoming PowerMac revisions remain a topic of anticipation...
Appleinsider claims that according to their sources, new graphics cards are not likely the cause of the delay for new PowerMacs as previously suspected.
A previous report pointed the finger at cooling issues with the new PowerMacs. Meanwhile, the new PowerPC 970FX based Xserve has only recently started shipping in March.
The next defined Apple event remains the NAB on April 18th, 2004.
