As a 34yo video gamer since the first day I could hold an atari 2600 controller, I can say that neither the iPhone, iPad, and especially the Wii have anything to offer that would hold my gaming interests, or my peers for that matter.
That said,
Why on earth would they stop doing what they are doing?
Unless they suddenly decide they don't want to be massively successful anymore.
The Wii isn't for me, but bashing it's gamer-base, games, play-style, and technical achievements (concerning video quality anyway) aside.
It was
making money since day ONE. It takes a long time for hardware to
make money.
Not to mention licensing.
As far as them "winning" the battle against Sony, that's a pretty loaded statement.
Sony wasn't trying for the same demographic as the Wii, that much is completely obvious. Sony and MS have the demographic they specifically targeted (me

and I'm willing to bet they are "winning" in that respect.
Also, consider the most successful platform ever, in terms of ownership and longevity, the Playstation 2.
Sony, not Nintendo made that.
Mind you, I don't own a Wii, but I like Nintendo, they are smart.
They hit a demographic that others forgot about, and targeted their price, and product accordingly, and hit a home run.
If I were Nintendo though, I don't know that I'd consider the iPhone, let alone iPad, a threat to your devices.
The iPhone can only play certain games in very certain ways and are thus heavily limited to due to interface, and, most importantly, Apple.
And finally, cost.
