Update: 10236 is shipping now.
I have a feeling that these "pre-orders" for the US market was actually supposed to be a genuine VIP early access deal, but maybe the shipping containers didn't make it to shore in time. Other than 10234 Sydney Opera House, 10236 Ewok Village
is also available for pre-order if you're a VIP member. Just make sure you're logged onto the site before hitting the above link. 10236 Ewok Village will ship by September 1, probably earlier, and will cost you $249.99 and provide you with 1,990 pieces and 16 minifigures.
