Little Big Planet is established IP on two systems with large installed bases so it has all the advantages I can think of here.

Bayo 2 should be able to have 1.1m.....if advertised right.

LBP3 will easily sell the most due to it being part of a fairly popular franchise!  Bayonetta 2 will sadly sell the least due to it being a WiiU exclusive!

LBP easy 1m+++

Even Mario Kart is a Wii U exclusive... 1,200,000 first week.

* niche WiiU exclusive

Seems like an unfair comparison.

LBP will likely sell about 3 million. It's a fairly popular franchise and currently one of the only offerings of its type on the console it's on

SO is a fairly unpredictable title. It will probably sell well because it's advertised as "adult" which is taking advantage of the disease setting the market up for its next crash. 4mil total.

Bayonetta is the odd duck of the group. I'll say it sells 2 million over the course of its life but it likely won't be the heaviest sales up front. I'll say it boosts sales for the console more than LBP or SO do for their respective systems.

I just have a feeling Bayo 2 is going to do better than expected. Look at how everyone underestimated MK8.

So niche that have more pre order of Smash Bros. XD

LBP3.
