The channel packages are already very close between DTV and AT&T TV and I expect they're going to get closer still as AT&T TV becomes DTV Stream (e.g. adding some or all among PBS, ION, INSP, NFL Network, and Cowboy Channel, while also filling in the missing CW and My Network TV affiliates).
But I don't see them configuring the pricing so that it's the same given DTV's higher installation and equipment costs. I don't see them getting rid of DTV's 2-yr contract either in lieu of a $300 up-front installation charge.
And then you also have the fact that additional TVs (as well as other screens) can be used for no additional cost with the DTV Stream app while you must rent additional DTV receivers for $7/mo each. Or if you want the DTV Stream box, you can buy them for $120 each (or $5/mo for 24 months) rather than rent them as you do with DTV. The two products have different underlying costs and so DTV will require a higher ARPU than DTV Stream. And DTV Stream will be competing against YTTV, Hulu with Live TV, and Fubo TV, which all have a lower starting price point ($65/mo) than AT&T TV currently does ($70/mo).
So all that said, I don't see a unified checkout system where you see a single set of prices and you simply check a box as to whether you want your service delivered via DBS or OTT. Instead, I think we'll see both options featured on a new
www.directv.com homepage and then the two services detailed on separate sub-pages, with separate checkout systems, from there.
DTV Stream will probably be what they mostly advertise. It will have its own slogan of "Get Your TV Together" likely referring to the fact that it allows you to watch cable TV via the same device/TV input/remote control that you use to watch streaming apps like Netflix, HBO Max, YouTube, Prime Video, etc. That's something you simply can't do on DTV or Uverse TV (or lots of traditional cable TV operators) given that those services' receivers lack streaming apps.
