Halo 5 if released for XOne, as it'll be overshadowed by Destiny.

Unfortunately there's no reason whatsoever to expect Bayonetta to sell even decently. I think sales will be significantly worse than the first.

well the PS4 has the biggest flops. 1.84 TF to be exact.
or is PC included? if so, the GTX Titan black edition will be the biggest flop.

I don't know why people are automatically thinking that Titanfall will not flop. There is always a possibility of a Haze fiasco witch boasted a new game mechanic or Lair. I'm thinking that the overhype will be its downfall. I have no idea how this game became the second coming. I have my doubts and will vote for it being the biggest flop.

Bayonetta dosen't have any hype and no one expects to do much anyways.

All of those games will probably do pretty well, except bayonetta 2. I just don't feel like it will sell well. The first one was only on PS3 and 360. Most of the people the liked that game are still gaming on the ps3 or 360, or they have the xbox one or ps4. Plus it only sold 2 million copies on those platforms which have a combined total around 160 million. I could be wrong, but I'm thinking less than a million units.

While I voted for Bayonetta 2 as well, the bolded statement is a lie.  Bayonetta 2 definitely has hype going for it, albeit from a rather small and vocal crowd.  There are also a lot of Nintendo enthusiasts who do expect it to do just as well (if not better) than the original.
