The Xbox One tried to be all-digital, look how that turned out. Phones have the benefit of accessing 4G networks. Consoles don't, unless you want to pay extra. Data caps & limited access to the internet are still real issues.
No Microsoft poorly made a peep with little to no details and poor information and messaging. Gamers freaked out. This was also several years ago.
Look it's coming. It already exists.
I find it funny you mention 4G in one breath as a positive and then Data caps on home internet as if cell phones and mobile plans aren't severely capped too.
What I was saying and it holds true, is that the general public has no issues with a digital only future. It already exists. People have little issue with Netflix and Prime instant video and other digital means. It's only a matter of time before it's the norm in games too.
And with Nintendo looking to unify their platforms it's almost a necessity.
Finally I love how you brought up the Xbox One story as if someone posting here wouldn't know about it. I mean we are discussing on a gaming enthusiast message board. It is safe to assume that most if not all of us have knowledge of some of the major news stories in gaming over the past 4 or 5 years.
