The thing you all have to keep in mind is that people like Steven Wilson and Neil Wilkes are the good guys. They create and produce the 5.1 mix, which is the important part. They have no control at all what happens to that product once it is completed.
I would wager that if you asked Steven, and I know that if you asked Neil, they would want these mixes out to the public in a stand alone or CD+ package without a huge price tag if it were up to them.
When a title like the EL&P is relegated to an expensive box set, it only means that fewer people will get to hear the results of their work.
I have not heard from Neil how the Tears for Fears surround mix will be released, in what format and what retail options. Funny thing is, they may not even know yet. All I can say is that the 5.1 mix is killer on the DVD-A that I tested, and I am sure that whoever purchases it, no matter what the retail option, will be pleased and glad they got the recording.
As for scarves, marbles, booklets, posters, and anything else that may come with it, well, that's a totally different story!
