To Larry: Yes, we are actively researching the combo 3.5mm jack. We found several sources and a number of parts. Most come from suppliers in China and not all of those suppliers are well known (read: we don't know their reputation for quality and delivery). We need to get through these issues. Some parts are substandard per our exacting criteria (optical transmission speed being too low, for example), others are so wide physically that we can't fit them in the space available. Others yet are looking promising. We need to finalize this soon and make the right holes in the side panels. Once we choose the final part I'll make the announcement. Hopefully next week.
This would be great. I've got a preorder in and this would really suit me as well. Thanks for all the effort.
