Microsoft has publicly stated that SQL Server 2008 will RTM in Q3. It is Quarter 3 now. Where is it? :-)
I'm sure that the final touches will now get taken care of now that Bill Gates is no longer a full-time MSFT employee. I'm sure that his "short-timer" attitude trickled down to the develpers working on the product and that the final dev work will be completed. (Just kidding!) Perhaps this will be an answer to a MSFT triva question some day - What was the first product to be released without Bill Gates as part of MSFT?
Now that we have already had the party for 2008, I am really looking forward to its release. It will be interesting to see how fast 2008 is adopted vs. 2005 and 2000.
