Infoworld wrote an article regarding the rumors surrounding "Macworld NY". They reference this site as well as Spymac.com.
The focus of the article, however, appears to be the Xserve and does contain some new information. One anonymous reseller reports that Xserve sales essentially halted after the PowerMac G5 was announced.
The article also confirms previous rumors of deep discounts for developers on Xserves, hinting that Apple is trying to clear the channel.
The only Xserve rumors available here have been relatively unconfirmed rumors regarding Xserve updates by September. One additional anonymous report that came in provides similar information with claims that there will be no Mac OS X 10.2.7 Server version... and instead the new G5 Xserve's will require Panther Server. According to these rumblings, Panther Server is expected shortly after Panther Client.
