I'm actually pretty sure that we wont have MM over here in good ol' England this time around. I went to TRU for the Ep 1 MM and there was a pretty good turnout with the press there etc. However, no Mauls and very few decent toys and everyone was quickly disillusioned (not that I'm suggesting that the good people at TRU purposely didn't put any Maul stuff out for Scalping purposes!) In fact the best thing there was the Star Wars Store card getting you point and offers on SW stuff - seen it? Got myself three of them and they didn't cost squat!
However, my reasoning for doubting MM in the UK is that stores got badly stung by buying HUGE volumes of Ep1 stuff that they couldn't shift. This is why we have the VERY frustrating situation of not having any stores sellin POTJ at all. TRU have absolutely NO Star Wars stuff on the pegs at all, except for a couple of stale EP1 products like Yo-Yos. This means that all new POTJ stuff has to be brought from scalpers. Ooops, I mean dealers. Same thing. I just think that no-one over here will take chances with Ep2 and there will be nowhere near as much stuff out on the pegs, or as much store promotion.
