Mega Man is not in.Seeing as the icon number theory has not been discussed, let's bring it up now!
Every "world" in the Smash Bros. series is represented with an icon, and that icon shows up on the Dojo site beside each update relating to that world.
If you right click on this image and check its properties, you will see that the url for this icon is
http://www.smashbros.com/en_us/images/icon/world_b_22.gif. See that number 22 at the end? That's what this theory is about.
Here are all of the icons that have been released and the number they are assigned to.
1. Super Smash Bros.
2. Donkey Kong
3. Star Fox
4. Kirby's Dreamland
5. F-Zero
6. Metroid
7. Mother/Earthbound
8. Pokemon
9. The Legend of Zelda
10. Super Mario Bros.
11. Yoshi's Island
12. Fire Emblem
13 = unknown 14. Ice Climbers
15. Animal Crossing
16. Wario Ware
17. Metal Gear
18. Kid Icarus
19 = unknown 20. Sonic the Hedgehog
21. Nintendo DS
22. Pikmin
The order of these numbers has a fair amount of importance. The first eleven are worlds that were present in the Nintendo 64 Smash Bros. game. 12 through 14 are worlds that were introduced in Melee, with the exception of 13, which is unknown. However, the only remaining Melee world that has yet to be announced is Game & Watch. Therefore, the likelihood of icon #13 being Game & Watch is exceptionally high.
Now, all of the numbers after 14 are worlds that are new to the Smash Bros. series, and are appearing for the first time in Brawl. Number 19 is blank, which confirms that there is at
least one more gaming world that has yet to be announced. When the Pikmin icon was discovered to be #22, there arose some surprise that the Pikmin world did not fill that empty #19 slot. So, not only does that slot need to be filled, but there is also now the possibility that more worlds can be tacked on to the end of the list.
It's kind of late to be mentioning all of this now that the game is only a month away from its release, but I think it's worth talking about at least a little bit. Also, I like being the first person to point out some cool new information, it makes me feel special. Well, not that this information is new.
