There's a discussion about the new toys over in the Star Trek XI forum. They've been on sale in the US for about a week I think.
Like you, I'm in the UK, and had also heard the toys were coming out officially Sunday 19/4. Good to hear that TRU will be selling them a day early on Saturday! Wonder if any other shops will be selling them from then, or indeed even earlier!? Any fellow UK-fans seen these in places like the Entertainer, Tescos etc yet?
Two of each!?
