Last night at a Super Target in Florida; I have found out that some of the new summer 2012 sets are/were released. The reason I know it was released last night is because the store had just restock the Hero Factory side of the Lego section and a few did not have a official price and so it did not show up on the store's computer "merchandise price system". The sets I saw was XT4 (I brought this set), Core Hunter, Voltrix, and Speeda Demon.
Speeda Demon set I saw; did not fit the shelf among the other sets (since its a rectangular shape box) and cost $5 more then its original planned price (which was $29.99). I did not see the Hero sets out yet so I am assuming they will be out in August 2012.
Also the sets that has those zipblock bags things has a gold color line above it instead of the silver color line that are on the January 2012 sets.
ANOTHER UPDATE!
On Sunday (my last day in Florida); I spotted Stormer XL and Bulk sets in a Toys R US Outlet store, but they cost twice as much as the other Hero Factory sets that I saw on Friday night. However I did not see Nex, the rumored Breez, Stringer, nor Thornraxx sets in that outlet store. BUT their pictures are shown on the back of Stormer XL set.
If you want to know how much they would cost in a Toys R Us outlet store (outlet store sold only some new sets; you have to go to the non-outlet one to see the whole selection); Stormer XL cost $36.99 instead of his orginal planned price of $20.99 and each hero sets cost $16.94 and same goes with Core Hunter, Voltrix, and XT4 if they are ever sold in that outlet store and also Speeda Demon set cost $40.99.
In a Toys R Us (I read their ad that listed some of the sets' prices); Stormer XL would cost $29.99 and Speeda Demon cost $39.99, Bulk, Breez, Core Hunter, and Voltix cost $14.99 and while Stringer and Thornraxx are $9.99.
Idk if retailers like Super Target and Toy specialty retailer like Toys R Us has all the Breakout Wave 2 sets released, but I had overheard rumors from Hero Factory fans (during my trip in Florida; at the Super Target & Toys R Us outlet store and while searching the Lego watchers' blogs) that Lego Company are still holding up on releasing them all due to now unknown reasons (previous problem was changing the prices in other countries, but does not effect Germany) and are slowly releasing some sets like releasing the villains' sets on Friday then on either Saturday or Sunday will be the heroes' sets being released.
