While we're all anticipating 6E, I strongly encourage you to check out Dust Warfare. The Rules were released at Adepticon in April and the game is really fantastic. I've done a relatively comprehensive gameplay first look here:

I have to be honest. I really, really like this rule set. Coupled with the fact that you can honestly and truly buy into the game with a competetive army for less than $100 bucks, and I think FFG and Andy Chambers have a winner on their hands.
We're going to do a modelling article or two on the walkers later in the week/month, but I encourage you all to at least give this one a try.
And yes, I know this isn't a 40k article None of you scroll down to the other wargames section!
As always, C&C welcomed.
Cheers!
