Yes, both the Vantage and Clipper themes have had delays previously, however they currently show
release dates which have not been surpassed, so they are essentially up to date. Other than any percentage difference which may change as progress is made, those dates won't be updated unless they cannot be met. At this time, the dates are still correct and on track. As we mention on the releases page, we recommend that you don't schedule projects around these estimated release dates.
