Ok, let's see... I could bet, that none of the big 3rd party developers aren't going to make their own console, since it doesn't fit their business strategy with multiplatform titles and in case of the console flopping, it would hurt badly their existing IP:s value.
So, it would need to be and outsider, or atleast someone, whos profit doesn't rely on game software (this is practically how Nintendo, Sega, Sony and M$ has entered the console market). Developing a console requires a lot of money, as well as retail relations (theoretically, even your local grocery could launch a console tomorrow) and relations with software developers.
Now, when you look at it, there's not many companies in the world, who fit the standards. I actually can only think of one company, who might enter the home console market next (although, Apple is not completely out of the question) and that would be Nokia.
Nokia has the resources, its profit doesn't rely on games, it has experience in hardware manufacturing, it has a ready retail channel, it has relations to games developers and publishers, it has internal software department and it has interest to expand in gaming. Although, i wouldn't expect a "traditional" games console from them, more like a PS3 kind of solution, an set-top-box with interchangeable games.
@Sky render: When you count how much Nintendo invested in Wii, you need to take into account their more than 3 decades of experience in making games. That was what they invested in Wii (and DS).
