Been waiting a while now for the LBS to get some pricing/spec details in but no joy yet, however just noticed it's up now on the Giant Oz site:
http://www.giant-bicycles.com/en-au/bikes/model/anthem.x.29er/7284/44211/

according to my maths that works out just over £2k which seems pretty good considering the spec. ofc it could end up more expensive/lower spec over here but I thought bikes were generally more expensive in Oz if anything? I was hoping they'd do a range like the 26" version but looks like it might just be one bike for now.

I'm still not sure about the looks of a full sus 29er. However that will be my next bike, no question about it. Looks amazing!

Looks like it's on the US site to but about £300 more (but less spec. detail). http://www.giant-bicycles.com/en-us/bikes/model/anthem.x.29er.1/7508/44088/#

Possibly UK site to if you mod the URL but no price on it there http://www.giant-bicycles.com/en-GB/bikes/model/anthem.x.29er.1/7508/44088/#

it's called the 29er 1 though on the US/UK sites so might be in more in the range after all
