I'd like to see the center-beam flats done again. It would be nice to see some better loads for them. I contacted Grand Central Gems regarding doing their lumber loads in O scale and they said they're looking into it. All depends on how great the demand is.

Wood chip cars are nice, but there were so many variants, it would be hard for MTH to do a lot of them accurately.
