@pittrek: Wabid's not trying to make a decision for the people who will be watching it, because they're free to decide to convert it (in most cases losslessly) to any format they might prefer. The only benefit of an MKV release that I saw (and still do) is that it is a way to release a high bitrate version before the BD with menus and all is ready. Then, when the BD is ready, anyone who is interested, can convert it to mkv if they're willing to put in a little extra effort (like 1 millionth of the effort I put into making the thing available to them and 1 billionth the effort of the people who made the movie) and if they're not willing to put in that effort, then they frankly don't even deserve to see it.
