I think comments like this are typical of industry social isolates like Guillemot who seem to believe that their whims and wishes must automatically be adopted by their customers. Many a time I've heard from industry executives about how this and that is going to be the future. They want absolute control over their products, so "streaming is the future". They want to kill secondhand sales, so "digital is the future". What the customer wants and buys never factors into it for these idiots.
And almost every time, barring a few obvious developments, they're wrong. Supply does not get to dictate demand.
The industry has an interesting knack of developing in ways that, really, nobody predicted, simply because it rarely develops homogeneously. New developments tend to branch off into separate markets instead of supplanting existing ones, unless the old tech really offers no advantages (see DVD over VHS, for instance). Back in 2000, people were predicting that 2D games were dead because all games would be 3D. Back in 2005, people were predicting that physical media would be dead by 2010. And here we are, in 2016, and not only is 3D not necessarily king and physical not dying, but business models such as indie developers that were previously digital-only are increasingly adopting physical. 2D accounts for a very large share of the market. The fact is that both co-existing to scratch different itches. And yes, the industry genuinely thought that OnLive was the future. Yeah, we know where that went.
So will it be with streaming. You only have to look at the trends with Netflix and co. to see where this is going. Industry apologist articles constantly write about "the death of DVD and Bluray" blah, blah, blah, but in fact, streaming has only killed off the DVD rental market. Similarly, in the music industry, the singles market is pretty much dead thanks to digital downloads, but CD album sales are still pretty strong. It's all about the advantages that physical ownership offers in respect of collectability, trading rights and resale rights.
The problem with such generalised predictions is that they grossly undervalue collectiblity, trading and resale rights and massively overstate the perceived inconveniences of buying physical media or digital downloads, waiting for it to arrive and install it.
These vocal predictions are designed to keep clueless shareholders investing, nothing more.
