Freerunner will be GTA02v5 or GTA02v6? (was: Fwd: Future Button and LED software spec)

I'm re-posting here some mails from the openmoko-devel "Future Button 
and LED software spec" thread [1] in which there are some infos about 
Freerunner hardware that I think they should be more visible.

Summarizing, they say that the GTA02v6 hardware version fixes an 
hardware bug that causes the LEDs to use about 150mW instead of 25mW.
Btw Werner Almesberger stated there that the first batch of GTA02 to be 
sold will be composed by GTA02v5 phones while GTA02v6 hardware will be 
sold only in a second phase.
The hardware differencies between the two versions [2] (I've updated 
with this LEDs issue) don't seem so worthless since there are some power 
fixes (not only this one).

So why shipping semi-bugged hardware if there's a fixed version ready?
