I'm also waiting for these to come out. I have a DCS51 that reboots if you knock the power wire the wrong way, and it has a few too many "quirks" with JMRI that I don't particularly like.
I trust TCS to get this right, so I'm less concerned about features or bugs, and more concerned about total cost. I'm hoping that TCS offers a package with the throttle and command station, but I'll probably buy both either way. I'm on a quest to get rid of JMRI, and this is just what I need.
