I was at the Glendale,CA Lego store today and not only do they already have the Series 4 figures but a NEW Hero Factory section!! However, they only have arm/leg joints, helmet accessories and armor pieces. And it's been there for a week. I asked if it was just there for a limited time, one guy said no and another said maybe, so I bought a cupful of joint pieces. If only they would throw in some ball/socket bricks, then I'd be set for life.
Any other stores have this yet?
