I noticed that too, but if you look at the top of the product page they say in very dramatic
style:
G0 Stepping in stock now!
...and under the Summary tab:

sSpec#: SLACR
Core Stepping: G0
whereas the bit about 'B3' under details hasn't
changed for weeks. They just forgot to update
that section of the page whereas they're basically
saying it's G0 in 3 other places.

Also I think they COULD be out of stock by Monday
since there's a lot of pent-up G0 demand.

Personally I'd place the order on the WWW NOW
and then if there's a place to put "comments"
or "notes" on the order process say you
want a G0 and if there's not such a place,
email them with your order number and
say you want a G0 and weren't sure if they
were guaranteeing that for all web orders
based on the product page. That way you'll
get your product 'reserved' and yet they'll
be able to see your G0 request before they
actually process your order Monday.
