I would like to see them do run of CNW diesels in Premier E6, yellow. I would love to own an AA set.
Also, a PS3 Railking Burlington Zephyr set -- have not done it since PS1. This is the flagship of Chicago's Museum of Science and Industry. If they sold it in their gift shop, they'd sell a ton of them and introduce new generations to our great hobby.
And, still thinking Chicago, how 'bout one of the new designs of the Metra engines that are in the works?
Just sayin'...
Merry Christmas!
Mike
