He said Ken Chahine told the attendees at the RootsTech conference that:

"Later this year, AncestryDNA will be releasing a “more granular” ethnicity calculator. You may recall that they updated the calculator just last year."

and

"AncestryDNA plans to release “new tools” this year, including improvements to cousin matching (which echoes comments made by Kenny Freestone earlier in the conference), and tools to “confirm family lines.” These two tools are AncestryDNA’s alternative to a chromosome browser. AncestryDNA has not yet provided a chromosome browser for several reasons including privacy."
