There's no official information that says that Dynamics NAV 7 is delayed. But if you take up the previous time frame of 2010-2011, and add the fact that all Microsoft will says is that release "is scheduled for release in calendar year 2011-2012", it looks like there's some sort of delay. There's no hint at which end of the rather loose schedules, either the original or the new one, in which the product will hit the market. This broke via a Twitter post from Rob Helm an analyst with Directions on Microsoft who follows Microsoft developments and that post had no information other than there would be a delay.
