Apeks have a new type of DS4 (called the Tek3) in which the ports are on one side of the 1st stage (there's a left and right version of this). I doubt this is going to be much of interest to us (certainly not for me as I don't think hose routing will be significantly improved, if at all), but still, I thought of posting couple of links in case anyone hasn't got anything better to do!

PS I bet there's couple of people over here with GAS - Gear Acquisition Syndrome
