Looks like some highly detailed ships, nice mat, overall layout seems good, each ship has its own specialty, but not sure I'll get it. GW has a decent string of photos up on its website for the game. Probably wait at least till I see and hear how it plays.
The limited release concept is marketing. Then they'll put out something else and folks will buy it too because thats limited and they'll want to have the in thing being played now. Its like when something gets put on sale, there's this psycology that tries to take over and say, "Oooh, I'm saving money", but really its getting you to spend money.
And yep, in New England, a person can find a copy of Space Hulk if they want one. I won't be rushing to buy Dreadfleet, and would rather spend money on other things. Besides, I enjoy MoW, and have plenty of fantasy and historical figures that need painting anyway.
