It's all marketing for home theaters, because they obviously need something new and improved in order to sell Screens and players.
I'll splurge for 8K SteelBooks if it becomes reality, but unless something blows up, I'm not upgrading any of my components for the sake of playing them.

As for the dents in the SteelBooks, some of you might not mind having a small dent, in other words unless you are OCD it might not matter. Myself, I choose to return them simply because I have duplicates coming from the US.

I just find it a real sad that for $50 a pop, the best you can expect are damaged goods!
