Hey, I fully expected games like Assassin's Creed and Call of Duty to sell a million copies each! How was I supposed to know how things would turn out?

Besides listening to Rol I mean.

By using logic and reason.

Troll. We're onto you...

No, really. I expected more from the Vita and less from NSMB2 than this.

I actually expected a bit more from NSMB2 than this, albeit only a few 100k more. I would have been quite surprised if AC or CoD went on to light the world on fire, though.

This is obviously a matter of dispute. The question you're bringing up here is a bit broader than Mario, and is really whether or not a franchise is linked to a genre. I'm of an opinion that they're not. Mario Kart, Super Mario Bros. and Mario Party 8 are all the same franchise, but with subfranchises in them. Similarly, LittleBigPlanet Karting is in the same franchise as LittleBigPlanet 2, Simpsons: Hit and Run is the same franchise as The Simpsons game, and World of Warcraft is in the same franchise as Warcraft 3. 

Oh, and for the record, Super Smash Bros. Brawl isn't counted as a Mario game. While Mario is in the game, it's not a Mario game - it's a franchise of its own. Some would argue it is, but I find that the best method is to simply go by games with "Mario" in the title.

Animal Crossing on 3DS could easily beat the top 10 Vita titles once it launches world wide.

Sure but it's pretty safe to assume Vita digital sales are a higher percent. Add in that lots of launch games are disqualified plus the much smaller install base and you can see how this comparison favors NSMB2. Regardless it is still pitiful that the Vita loses so badly.

This is more one-sided than expected...good prediction!

It looks pretty bad for Vita, Kudos for Nintendo. Still, I seriously think that this fact alone doesn't matter much. Remember, this is a Nintendo franchise. 3rd party games don't sell nearly as well as 1st party games on 3DS and this is very important. 3rd party devs will support Vita if the sales of their games start to pick up there, even if 3DS outsells Vita 8:1, but only manages to sell 1st party games. The sales of 3rd party games are better on 3DS right now, but it's not an impressive number. The 3DS is saved for Nintendo, they will make money on it, they will sell their games on it, but they still have a chance to repeat the Wii. But Sony really needs to catch some wind in its sails, keep selling at least 60-70 thousand Vitas per week and get a few more good games that sell really well (around 1 million). Nintendo is safe, but Vita can still win its own war. They have to convince 3rd parties, that their smaller install base actually converts into bigger sales of 3rd party games.

@Scisca:
okay, lets look at 3rd parties real quick:

Vita:
1. FIFA Soccer (.37mil)
2. Rayman Origins (.25)
3. Persona 4 (.24)
4. Assassins Creed (.22)
5. Hatsune Miku (.20)
Average: .256mil

3DS
1. Monster Hunter 3G (1.60)
2. Kingdom Hearts (.95)
3. Dragon Quest Monsters (.91)
4. Super Street Fighter IV (.86)
5. (skipping Mario and Sonic) Lego Star Wars (.65)
Average: .994mil

in fact, there are thirteen 3rd party 3DS games that sold more than the top selling vita 3rd party game. That'll be a tough sell for Sony...
