They only started releasing the weekly builds after 1.0 so you've only seen one example to compare it to. Settle down.
As for when it's coming out, I don't really care. Most SMP servers won't update until after bukkit and other mods also get updated.
Bukkit doesn't take too long to get updated. But I do agree with you, there's no telling how much work they're dedicating their time to after the official release because it's only 1.2. Just inspired me to start a thread "Minecraft 2.0" in the Minecraft Survival section Brb
