Where did you see that? AT&T has always maintained that the new IP version of Directv would be a separate product from Directv Now, which would continue in its present form.
Dropping a product that has a couple million subscribers doesn't sound too likely to me, especially when they wouldn't have anything to replace it. The new IP version of Directv requires using Directv supplied clients, and will almost certainly be more expensive than Now, so they'd lose many/most of the Directv Now subscribers if they did that.
I don't believe it unless someone can produce a statement from AT&T saying EXACTLY that, not an article containing sourceless rumors, or some wishy washy statement from AT&T that can be interpreted in multiple ways.
