Sony or Nintendo.
As a company, Sony continue to bleed money from almost every orifice. By the end of this gen, PS3 was nearly pointless as a business endeavor. Vita has been a colossal waste of time and money so far. Sony probably still have enough cash in reserve to make the PS4 directly competitive, but I predict a much more conservative Sony from here on out. Then there is the issue of failing to deliver key titles in a timely manner, such as Gran Turismo, Final Fantasy Versus XIII and vaporware like The Last Guardian. When PS4 does hit, how long will we have to wait for the big games to hit the scene too? Ironically, only their Western studios appear to have their act together in this regard.
Nintendo are doing well with the 3DS (I guess, since they were selling it at a loss for a while), but their Wii U has been disastrous. Like the Vita, its 2013 looks grim and they are in desperate need of their first party stable to push something major out like a 3D Super Mario game, Zelda or Super Smash Bros (which we are told we have to be patient for..). Third party also needs a ton of convincing since their support looks lackluster - no GTA5, no MGS, no Tomb Raider, no Crysis 3, late BioShock. Then there is also the issue of power - the Wii U is in some cases even failing to live up to current gen standards. Once the big boys arrive with their Unreal Engine 4s, I give what little third party support there is for Wii U about 2 years.
