While they say "DVDs" they do not actually mention Blu-ray until the end as a note, so this litterally may be misinterpreted where DVDs will be gone but Blu-ray will still be around for quite a while longer.

With the growing promotion of 4K UHDTV, it is pushing streaming sites to spend more millions to increase their infrastructure to handle even heavier traffic. People who decide to go with the 4K route will not be satisfied with DVDs or DVD-quality streaming just as people with HD cringe at the thought of VHS quality.

So even if DVD goes away, I believe Blu-ray will still hang around for a while to accommodate those who would prefer not to stream an iPad-quality stream to their 60 inch TVs.

The only 2 TV shows I ever tried to stream were Stargate Universe (which we abandoned after only a few episodes because it was stupid) and a couple of episodes from a new season of Supernatural because it wasn't available on physical media yet.  We HATE commercials, and as it turns out we were unable to get away from them with streaming.  It became just as much of a PITA to mute commercials (they were always so much LOUDER than regular TV advertising) every couple of minutes as it was watching TV, so that didn't last very long at all.

We really have no interest in streaming anything let alone buying a digital download of something to watch on our TV (absolutely will not watch anything like that on our computers).  I own 800+ DVDs and BDs which will carry us through the years with everything we could possibly want to watch.  Having said that however, there will still be movies/TV shows I might like to add to my collection.  If physical media goes south in favor of digital downloads, I'll still have my collection but it will piss me off that I can't own physical media of potential wants. 

I honestly believe physical media will be around for quite awhile.  I don't think studios/media companies are that stupid (at least I hope they aren't).
