You left some items out:

Superman - New head, cape, lower arms, boots and crotch piece

Wonder Woman - If the cardboard cutout pic is accurate, it's almost an all new figure. I just compared the single release to the pack and it looks like she has an all new skirt, head sculpt, upper torso, and lower arms. I'm pretty sure the New 52 WW was just going to be the rerelease of the single carded figure
Aquaman - From the first release, pretty much just the shoulders, biceps, and upper legs look to be reused.
Batman - Based on what the New 52 figure that was shown, new lower arms and hands, new head sculpt, new cape (very hard to tell but you can tell bc the Rebirth cape goes more over the shoulders than the the New 52 one did and has less tips on the bottom of the cape), and new crotch piece. It looks like the feet are from the new 52 but I can't tell if the shin piece is a reuse of the series one Batman (the New 52 had more armored look to them).

Maybe we use the term repaint differently, but to me, it means all same parts, just repainted. I will say that I will be a little ticked if the Batman is as short as the series one. I think he will be taller with the new feet and headsculpt but it will be hard to tell until the release.
