You're suggesting that they hold off on releasing the BIOS until Nightshd finishes tweaking Xbtool for it, simply because you need it to boot to F:\avalaunch.xbe? I'm curious as to how selfish a human being can be if they say they don't want anyone else to have the BIOS until they themselves can use it to their liking.
Here's the way it works. The BIOS devs release them when they release them. Nightshd releases a new build of Xbtool when he gets to it. Most people are not delayed. You sit and wait and patiently for these philanthropists to get around to your agenda. You don't connect to Live in the meantime. If you don't like it, tough luck.
