There are over 100 shortprints in the recently released Topps Heritage Football.  Even though it has not been officially confirmed by Topps, information from collectors/dealers which are breaking large amounts of product points to the following cards:

95,100,101,107,109,111,121,123,125,127,129,131,133 and 311-407.

There are two different versions of cards 1-90.  There are red back and blue back versions.  Though they are not technically shortprints because the combined print run of the red and blue backs equals cards 91-310 there will be half as many red or blue backs as compared to non-Shortprinted cards.
