Just saw these at TRU. They are 2x4 bricks that transform into minifigures. Then you add the armor/weapon pieces and you get one heck of a minifigure. They also come with extra pieces for further customizing. The only drawback? The price. The pack of 3 figures was $17.99. They also have buildable sets, but I passed on those not knowing if I was going to like the figures. I'll be picking those up in the near future.
