###New books will not be labeled Legends, but it is possible that material from Legends (such as Grand Admiral Thrawn) will be introduced into canon

"Legends" is a label used for past EU works:

Demand for past tales of the Expanded Universe will keep them in print, presented under the new Legends banner.

New books would therefore not be considered Legends by definition.

Furthermore, all Star Wars creative development is under the supervision of the Lucasfilm Story Group, so Disney will not allow other authors to write new non-canon works:

Under Lucasfilm President Kathleen Kennedy’s direction, the company for the first time ever has formed a story group to oversee and coordinate all Star Wars creative development.

That said, Disney is not discarding the EU entirely. Authors may be allowed to bring Legends material into canon if the Lucasfilm Story Group approves it:

While the universe that readers knew is changing, it is not being discarded. Creators of new Star Wars entertainment have full access to the rich content of the Expanded Universe.

So it is possible that Disney will bring more Legends material into canon (indeed, Disney has introduced Grand Admrial Thrawn into canon). This canonized material would obviously not be able to contradict other canon, so elements of Legends which contradict with current canon are effectively a dead end.
