So in Tiger's blog post, he states that it's mutations that make the new coats and species pop out from the free updates. I get that, but that leaves me with a question.

Since mutations are "rare" occurrences, and most are unlikely to get a mutation, then is our only remaining option to get these new coats and species through a purchase on the secondary market?

I think it's a valid question. If the answer to that questions is "no", then please explain how we are to go about breeding for these new coats without purchasing the genes if they only come about through mutations, since this is a breeding game and all. Afterall, you don't breed for mutations, and they don't happen often.

Not looking to bash MS or Tiger or anyone else, I'd just like a little clarity.

Thanks in advance.
