Mearl's spoken statement* sounded like he meant campaign/ storyline adventures. Level 1-10+ adventures. He could mean more collections of modular dungeons or short adventures.
* It was an offhand non-written statement, which increases the odds of him mid-speaking.
I don't think it was that offhand. But yes, that means they won't do two campaigns in a book a year anymore.
They will almost certainly do a sequel to Tales, and seem to already be planning for it.
