Strictly limited to 500 copies, the The Chaos Collection to be released in November (pre-orders sometime in October presumably), is a big unknown right now to most of us. Well, this hopefully answers what it is, and those of us within the hobby that are interested can now start setting aside some loose change for it.
please remember that these are rumors until we have an official announcement. so use your tiniest grains of salt on this one.
