Cutting the cable, lets talk options and media setups

I'm about to cut most of the cord.
I'm about to sign up for the PlayStation Vue. I can't cut it 100% yet, because there are some things I will require that Vue or sling can't get me. which mostly is local stuff. EATEL has a basic package for $20. I will eventually get a good outdoor antenna and a standalone DVR to take care of this issue.
I can handle going back and forth between different apps/streaming sites instead, but my wife will struggle. I have to bring her in slowly. after about 6 months, I expect to be cord free.

question: will the 50 mbps internet be sufficient to stream Vue on 4 devices if needed. 90% of the time I wouldn't have more than 2. but on rare occasions, it could be 4.
