I'm telling you, when I bought an 8-core Mac Pro last night, the sales rep said that they were letting their stock of 8-core machines deplete. Intentionally. This is an online store that has the word "Mac" in their name. Why would they do this? Unless they knew something was coming along to replace it and didn't want to get stuck with old stock...? The rep told me it would be wise for me to not open the box when I got it, so that I could return it for a new machine with no restocking fee. The strong implication was that a new machine was imminent.
I personally suspect the "end of Mac Pro" rumor was designed to create a rush on existing Mac Pro stock before the new machines hit the market. My 2 cents.
Then why did you buy 1 if you think a new 1 will be out soon ? I don't know if they will or not But the move to final cut pro x Is an indication they're moving out of the pro market which makes sense because all of their other hardware is consumer or prosumer.
