It looks to me like the picture labelled ANZAC land units is actually British land units: 1 UK artillery, 1 UK mech infantry top view, and 1 UK mech infantry side view.  I think the color is just off because of the lighting used for the picture, because when I ‘zoomed in’ on the pieces, they looked beige, not dark gray.

For me: Not yet.
First I have to read the rulebook.
Then I have a bunch of pieces on order from HBG that I’m going to use to replace some of the pieces I don’t like (and they should arrive by mid-week next week).
Then I have to talk my stepdaughter into playing a game with me.
So right now I’m looking at the end of next week before I play it.

I ordered mine from Amazon on 7/5, and received it 7/11.  I did the super saver shipping (free shipping for items over $25).  When you realize that getting it from Amazon for $29.99 with no tax and no shipping is about the same amount as getting it from CoolStuff for $19.99 plus tax (because I live in Florida) plus shipping, then it was a no-brainer to get it from Amazon now instead of waiting to get it from CoolStuff later.

Has anyone determined what the pieces model?

It looks like all infantry pieces are based on previous versions, and are unique to each country.
So the 16 new molds are 8 pieces for the Allies and 8 pieces for the Axis, which I have only identified as so:

Allied Tank:  USSR IS-2
Allied Fighter:  US P-40
Allied Bomber:  UK Lancaster
Allied Transport:
Allied Sub:
Allied DD:
Allied Carrier:
Allied BB:  UK Hood

Axis Tank:  G Tiger
Axis Fighter:  G FW-190
Axis Bomber:  G He-111
Axis Transport:
Axis Sub:
Axis DD:
Axis Carrier:  J Akagi
Axis BB:

Can anyone else fill in the blanks?
