Yes, the Blu-Ray will clearly be better in terms of the amount of content, most of which will be the same or greater quality than the DVD-A, but here's why it's important to offer both (from the THRAK Q&A):
2) Some fans want both - especially in America where a number of in car systems are DVD-a compatible.
3) Some fans want both if they currently have DVD & intend to buy a Blu-Ray player.
4) By including all options we can make it usable by the widest possible audience. None of the Blu-Ray or dvd/dvd-a discs are region locked & the dvd-a is a hybrid disc fully compatible with all dvd players.
And 5) I like DVD-A because you can very easily rip it on your computer.
