While I certainly support the purchase of DVDs, let's all note I live in Australia and that means an even longer wait. So while you guys have your Cartoon Network and whatever else, I've got to wait longer for
Madman to release it. That and the fact that you get 3-4 episodes per DVD, the release shedule is horrible long and costly. It takes a fair while for the 'box set' to be released as a whole, and for a good price. So while the wait is probably not as long as it is with video games, it's still hard to wait.
Yes, Tsubasa Chronicle will get licensed, if no one picks it up it'll be one of the most stupid moves by the American companies I've seen since the Naruto dub. Then again that was recent! Dubs do not matter, I certainly do not purchase DVDs for the dubbing, I purchase it for the original.
The entire point of fansubbing is to show the west the power of Japanese animation before the long wait for the DVD release, not to shift sales from them. If you really support and enjoy anime then you surely must purchase and support it's legal distribution in the west.
That said, go go Live-Evil!
