No dates as yet, but the prices for the new superheroes sets as follows (rounded to the dollar) taken from the [email protected]
The only way I could check the prices was to look at the product on the US site then change region since they can not be located on the Aus/NZ site.
$90/$90/$40 6857 The Dynamic Duo Funhouse Escape
$23/$30/$15 4527, 4528, 4526 construct a heroes
$25/$25/$13 6858 Catwoman Catcycle City Chase
$40/$50/$20 6862 Superman™ vs. Power Armor Lex
$130/$160/$70 6860 The Batcave
$100/$120/$50 6864 The Batmobile and the Two-Face Chase
As you can see most of the sets are on a heavy mark up from the US price with most at around 100%. Set 6857 which retails at USD$40, is effectively a 120% markup at AUD$90!! Guess the best idea is to wait it out till they are available from amazon or B&N.
I do find the mark ups from the US prices, and the difference between Aus/NZ prices very strange. For example the construct a hero is more expensive than the catwoman set in the US, but in Aus the catwoman set is more expensive. These sets are very similar in size (with catwoman probably being a smaller box) and can not see why the higher price point switches which removes shipping costs as the answer. Maybe they just figure they can squeeze a few more dollars out of us.
