Woodcrest June 26th. XServe Too?
An unverified MacRumors source had previously reported that their XServe shipment had been put on hold due to a back order of parts, and according to Apple the parts would not arrive until June 26th. This would seem to indicate that Apple plans on announcing its Intel-based XServe on or around June 26th. Of note, ThinkSecret has previously reported that the XServe was not due for release until July.
Exact specifications of the rumored Intel-based XServes are still unknown.
