While searching the web, I came across a German website that contains several Elite blasters not yet announced, their *European* prices, and their release dates.
After our friends at Urban Taggers posted that Hasbro Australia had released the release dates for the below blasters, I am fairly certain of these dates. The German word, "Veröffentlichung", meaning "publication" in English, apparently shows the release date of the following blasters. Keep in mind that these dates are still highly speculative at this point.
Stockade: January 31, 2013
Rampage (With Shield!): January 31, 2013
Firestrike: January 31, 2013
Strongarm: January 31, 2013
