I've just recently purchased the 'new' Icom IC-8600. This doesn't have the ability to directly receive DMR -- however, connecting a USB cable from the rear I/Q port to my PC and running HDSDR as well as DSD+ I am able to decode DMR. A long-winded work-around but it works.
So it's the same as the DV-10 not having a 'trunking' feature; I put this down to AOR manufacturing a worldwide general receiver. Trunking is used a lot in the United States and most people seem to favor Uniden receivers for trunking. Here in the United Kingdom we don't have trunking so that's a feature no one can use.
Just buy a cheap Uniden receiver that has trunking capabilities and just use the Uniden just for that -- for the rest of what you want to listen to; dig deep into your pocket when it's released.
