They've done some throwbacks. Not as cool as Heritage, but they did Magic Photos (Hocus Focus), which from what I saw wasn't too purty. They did some Bowman minis a few years back as inserts which had me wanting to collect foosball for the first time since about 1991. As a matter of fact, thanks for reminding me.
I have the Cobb RC, all I need are the rest.
I'd say they Topps has some Heritage Football on the slate. With the beautiful early Bowman and Topps designs, how could they not?
