SRP for the Arizona is $289.95.
There were some significant pre-release/pre-order discounts at Internet hobby shops for the Arizona, but there still appear to be reasonable discounts available on line.
Arizona is represented as being on "a one time production run.” Have not heard the Akagi refered to that way in any reviews/marketing.
I invested in this kit because it appears to be a complete departure from the Revell kits which so many of us built and/or have in memory as a reference:
974 plastic parts, 76 photoetched parts & 23 additional metal parts; Lifeboats & transport boats; 12 metal gun barrels & range finders, mounted on a pivoting turret; Metal propeller shafts & gun axis; Metal anchor chain with detailed anchor; 4 sheets of photoetch containing 76 parts for all handrails & cranes; Single piece 36.5 inch long hull with single piece deck; Two OS2U aircatft with positionable catapult; All guns elevate & traverse on a pivot; Heavily detailed mast & bridge with lots of photetch.

Some discussion on the above thread about first impressions of "test shot" regarding accuracy and assembly sequencing:
Here's a specific quote in the thread:
"Gotta disagree very strongly with this. I've been working extensively on one of the 1/350 kits within the past week so my memory of it is quite fresh, and this new one they're showing here at the Nationals isn't even remotely similar to that. The *only* similarity is in the hull and main decks, and that is just the split locations; all details are completely new. From the deck up (and even within the deck), absolutely nothing is even close. Look at the photos posted - midship splinter shields are separate pieces. The casemate guns are open, not rotating cylinders like all other plastic Arizona kits to date. Superstructure assembly does not have you trying to match the upper and lower halves of portholes on every level. This is not just refinement of a scaled-up kit. That's akin to saying Hasegawa's 1/350 Akagi is just up-scaled refinement of their old 1/700 ones. And even if Trumpeter started their CAD based on the lines of the 1/350 kit, it's just that: a starting point. The result I see is far removed from that."
I have the 1:350 Akagi - a beautiful kit, which I've just started assembly on, having slowly accumulated the PE and wood deck aftermarket items. But you might want to grab the AZ first.
White Ensign Models is preparing a supplemental PE fret (not yet shown on their website), and Trumpeter has a small supplemental PE set that is already available for the AZ kit.
