With 6TB being 100+ movies, that's enough for me. If you can afford and want K, you probably have 100 Mbps internet or better. 100+ is a lot of movies and the system software should smartly manage it by autoremoving the oldest content first or allowing you to protect movies from auto delete so your favorite content is always present.
Not at all the way I would interpret it.
First, 100mbps Internet speed is more of a function of how fast it is available where you live, not how wealthy you are. If you are a wealthy farmer but live 15 miles out of town, you are not likely to have a fast Internet connection speed. I have a fairly large business but we are in the country and the best speed I can get is roughly 1mbps. The houses in this area are stuck at that same speed.
Second, 100 movies is not really a lot - especially if you have a family that is dividing content. Game of Thrones type content for me, Twilight type stuff for my oldest daughter, chick flicks for my wife, Narnia films for my middle daughter and then the disney fare for my toddler and we each have a much more limited selection. My existing Premier line is 60TB after covering RAID and is 99% full. I might be able to pare down my content, but I am not going to be able to reduce it 90% without having a lot of disappointment.
Having to reload content effectively makes it no longer what it was - everything on tap. Instead, it becomes a glorified 100 disc carousel content wise and just has less lag time to switch between titles, but way slower to add a new title.
Putting the Encore side by side with the Premier is saying "This won't do everything, buy another system." That can be met with, OK, maybe I should buy the Sony/Amazon/Apple/any other brand in the world one for a lot less money. The convenience is gone when you have to sort through two different movie libraries from two different devices. Even if they were cataloged on the same device, to be told "to play this movie, please switch over to another input" really takes away from the elegance and the idea that a kid can use the system.
I have had a Kaleidescape system since 2003, so 12 years on and not once have I ever knocked the product publicly or privately. I am also a dealer and a huge proponent of it, but if the Encore and 4K is excluded from the Premier line, this entire thing is a dead end product for me. That would really suck for me, as I have three complete discrete legacy systems, the largest of which has two 3U servers, six M-class players and a couple vaults. That won't migrate into the Encore line and I won't run two systems side by side - that is just silly. After all, I don't have a Blu-ray player for Blu-rays, a separate DVD player for DVDs and then a CD player for CD content in any system in my home. To do that with Kaleidescape would be crazy.
I don't think they could be so shortsighted as to exclude 4k from the Premier line. I expect it to be rolled out when they have the 4K disc based content hit the market and then we will see 4K variants of the M300, M500 and M700 players. The 4K store isn't going to roll out until Q4 anyway so we will probably get that too, at least those of us in the USA will.
