Expect a big diamond theme to be used in the insert sets. The die cut set (Halladay) and the duo theme is back (Diamond Duos). There looks to be mini cards and possibly two sets of retro products one looks like a reprint set like 2001's Topps Through the Years set (see Jackie Robinson card), the other looks like another History of Cards set (see Babe Ruth). Shinier parallel cards (the ones that look like they're encrusted in Diamonds: Jeter and Ichiro).
More analysis later. Got to run.
