hmm, I think Sony.

I think Nintendo because of SSB3D, SSBU and Pokémon 3DS.

I would say Nintendo > Sony > Microsoft.

Nintendo doesnt make a loss on Wii U's and got smash and pok'emon coming out.

Sony got little big planet, wich shouldnt be a huge seller, but are probably making a profit on ps4 sales. Microsoft is probably taking a loss on the X1 and i think Halo MCC wont be a huge seller since its just an HD remake and X1 has a 5-6m userbase.

This got me thinking. Will ninty go all out next gen or play it very safe?

I predict their next handheld to drop as much as the 3DS did if not more. Their next console to drop too. So if they go all out they will lose billions but if they play it safe for a day 1 profit and very low costs they will probably flop anyway and increase their profits slightly.

NIntendo >>> Sony. Impossible to say anything about MS

Im not sure Sony is making a profit on their crazy bundles though...

I think its obvious MS will make the lowest profit or maybe even a loss. They are selling their console with a free game worth $60. Also Xbox Live gold subscriptions would be falling as more 360 owners upgrade to a PS4. 

Maybe, but we don't have any data from MS, so is impossible anyway

I think with Nintendo probably has this in the bag after seeing the explosion from amiibo and smash related sales....

Nintendo
Microsoft
Sony
