EA: Free-to-play can be "as profitable as a console game"

"The free-to-play group inside of EA Games is growing extremely fast - we've got 17 million users, 4-5 services stood up right now."

Free gaming has never been bigger, and it's likely to grow more as large publishers like EA take interest. "It's a very exciting time from our perspective because it's not all about consoles," says Gibeau, "it's about smartphones, tablets, free-to-play, browser, social."                                                                                                        http://www.pcgamer.com/2011/06/29/ea-free-to-play-can-be-as-profitable-as-console-games/

earlier this year in February EA said that "Free-To-Play"(and online) is becoming it's core business model
& late last year in November 2010 EA said that the Free-to-Play Market Will Threaten Console Business
now @ EA they're saying this,
 

Games industry seeing biggest transition in its history - Moore

Companies that "rely on the old model" will "die off" within three to four years

The game's industry is in transition. Smartphone gaming, social gaming, digital and cloud content delivery, free-to-play and a new console generation - big changes are ahead and the games companies that don't keep up will "die off" within three to four years.

With all that said,

These freeium games can be quite hardcore, robust and varied offerings (sometimes major IPs, and from big developers) covering nearly all genres competently comparable to their console counterparts.

Well Roma, if your product is good enough, people will be willing to pay for it.

That’s true

Still new with this so I have a lot to learn :)

I think nintendo should embrace this hype and let 3rd parties like Facebook Valve and EA create their own channels on the Wii U. Nintendo should believe in their own power to make quality games and should see these free to play models more like an extra reason why people buy a Wii U.

It is assumed that Nintendo always has made money on their sold hardware (besides the 3ds after the pricedrop, I'm not sure they still make a profit there). Therefore every concoles sold is a profit for Nintendo and another household won for the Wii U install base.

Furthermore Nintendo would still be the biggest influencer on the console and therefore have a mayor competative advantage compaired the Facebooks or EA's in this world. Other parties will only have a Channel where they can do their activities where Nintendo can do them system wide, with multible channels.

Also Nintendo could demand a fee for giving EA, Steam or Facebook acces to their divices. Systems like a certain percentage of profit or download fee would be logic. For instance if I want to play farmville on my wiiu and I buy some points from zygna and 5% of that money goes to Nintendo.
