I should probably add this comment as well. For a long time, MRC powerpacks were the way to go. If you had a layout, or were building one, everybody would tell you to get one of the MRC ones. Eventually, you may go to DC Cab control, but a lot of folks would power things with just a couple of powerpacks using block switches.
Nowadays, DCC rules. Many folks are starting right out with DCC, though for the real small time operators, DC will still work. But, it's mainly a transition time for the powerpack industry.
MRC has to change with the times. I'm sure they've lost market share; while DC still has a following, the majority of the serious MR hobbyists will be running DCC. And that just seems to me that MRC will be left out unless they offer something in that line.
