I dunno Mario Party 10 could go either way I guess. The Amiibo bundle should sell out, and Mario games in general never flop (even the spin-offs), though Mario & Sonic Olympics didn't do so hot.
I'll say
Tearaway PS4
Devil's Third
Also while not a full on flops, I think Xenoblade will sell along the lines of Bayonetta 2 and Splatoon along the lines of DKC: Tropical Freeze.
