MMM v3?

So elsewhere on this forum there has been some acknowledgement by Castle of possible case issues and I believe that there has been some BEC issues. So when are the MMM v3's due to come out?

I'm sure I'm about to doom myself by saying this but I've got a working MMM v2 right now and I want another but I'm waiting for the case and other improvements of the MMM v3...just don't know when to buy it...

Anyone have any news on this?

Thanks,
