This is fun to think about. I have some things I want to see as a gamer, and some I want to see as a Nintendo shareholder, things that would help them be successful. My perfect scenario:

1st party games:

-Super Mario Universe is shown. It is innovative and beautiful. Stunning visuals. Open world to some extent, but with classic style levels. Major MiiVerse connectivity. Uses some unique gamepad multiplayer that is fun. Releases November 2013.

Agreed.  That is most likely.  I don't think it'll be titled Universe though, but I see it coming at that time.

-MarioKart U is shown. Same as above, except not "open world". Releases December 2013.

Once again, agreed.  That is most likely.  I don't think it'll be titled Universe though, but I see it coming at that time.

-X is fully revealed. Epic visuals and sound, intuitive touchscreen controls of secondary characters. Gets major 1st party push as hardcore title. Has multiplayer. Launches December 2013 or 1st half 2014.

Much more likely because of the success of Xenoblade, but I doubt it'll be ready by December 2013.  2014 is a better bet.

-Zelda WWHD coming Sept 21, 2013.

Agreed.
-Zelda U is teased, visuals are breathtaking, action is fact-paced, art style is realistic/shadow of the colossus style, open world, multiplayer control of some kind - maybe a sidekick. Coming fall 2014.

Again, agreed.

-Retro's game is revealed as a new sci-fi shooter IP, or a complete re-thinking of Metroid. Co-op and vs online multiplayer. Awesome visuals and setting. Release October 2013.

That I'm a bit iffy about, but anything from Retro's gotta be good.

-F-ZeroU in development through a 3rd party partnership, release 2014.

3rd party partnership likely, but F-ZeroU, no.

-F-Zero GX HD e-shop release fall 2013.

No.  Not likely.

-Wii Sports U released October 2013. Uses 2 gamepads.

Maybe but I'm not sure.

-A new, unique IP released November 2013 that uses 2 gamepads in cool multiplayer ways.

Possible.

-Smash Bros 4 is teased with amazing visuals, will release summer 2014.

Agreed.

-Last Story 2 is announced to be in development.

Very possible, and yes absolutely.  Mistwaker and Monolith Soft are both becoming the new SquareSoft.

1st party other:

-WiiU Basic no longer on sale.

Good idea.
-WiiU Deluxe now $299.

Might be a tad too early, but yes, a price drop will eventually be needed.
-WiiU White 32gig with WiiSportsU, Wiimote and Nunchuck on sale October 2013, $349.

Somewhat possible, but I doubt it.
-Previous WiiU buyers get free download of F-Zero GX HD.

Once again, I doubt it.
-WiiU Black COD MW4 bundle with pro controller, fall 2013 $349.

Very possible.
-New version of 3DS with sleek black or white finish revealed, has upgraded WiiU connectivity, possibly can act as a second interface.

We'll see, I'm not so sure about this.

3rd Party:

-COD: MW4 on WiiU.

Most likely.
-Watch_Dogs and ACIV shown.

Absolutely agreed.  We know both of those two are coming.
-Final Fantasy XV is coming to Wii U.

Oh how I hope this is true.  Actually, it may be a while off, but I DO see FFXV on WiiU happening.  Square-Enix knows it too.  And hey, the FF MiiVerse leak was there, so... it COULD happen.  But yes, I wants it!  Realistically, though, it'll probably be multiplatform.
-Dragon Quest X launching in the west August 2013.

Not so likely.  If it does come, though, great.  If it actually does, probably not until next year.
-GTA V launching on WiiU the same day as other systems.

Very possible.  Especially considering the leak about GTAV for WiiU and PC from retailers a while back.
-Metal Gear Solid: Ground Zeroes coming to WiiU.

That's probably what the mysterious "Metal Gear" was referring to.
-Destiny coming to WiiU.

Probably not until next year, though; it is a timed exclusive.  But otherwise, maybe.

Also, a slew of 1st and 3rd party quick-play apps to be released. These cheap downloads offer a tablet-like experience.

Most of this I think is likely, some possible and others a bit dreaming. I can't wait for e3 though!
