Oui effectivement le modèle A consommera moins que la modèle B car on supprime la puce lan9512 (celle près des ports USB qui chauffe bcp :p). En contrepartie de cette sobriété, on perd la sortie lan ainsi qu'un port USB.
Certaines personnes sur le forum ont réussi a transformer leur modèle B en modèle A en passant outre la lan9512.
Il n y a pas encore de dates de sortie précises pour le modèle A, peur être fin 2012:

It is. We don't have a definite date at the moment because that has to do with how quickly the distributors can get on top of the current backlog (which is massive) along with some other stuff; we're tentatively saying we'll start making them in September, but that's VERY subject to change and doesn't necessarily reflect when they'll go on sale.
Si tu veux tenter de passer outre la puce lan va voir ces topics: http://www.raspberrypi.org/phpBB3/viewt ... 23&t=10393

Actually, I've got one.
Ok, it started out as a B, to which I took a scalpel.
I had to remove some of the connectors to be able to reach all sides of the 9512 - ethernet, USB, sound jack, and the JTAG row of pins, and afterwards put back the USB and sound jack. Then the scalpel on the legs of the 9512 disconnected that, and a bit if wire on R36 & R37 to connect the USB back up.
Why didn't I just unsolder the 9512? 'Cos it's soldered underneath, and I haven't got a hot air gun.
Why did I do it? Well!
Actually it was to see if a model A would suffer from keyboard stutters.
I've got a wireless KB/mouse combo that stuttered. It stuttered despite having 5v on TP1-TP2, and even after the Pi-pass for the USB power. It also stuttered on a powered hub.
So now on the A it doesn't stutter. Only - it doesn't stutter on the B, either. So it proves nothing!
But I've got an A
