Theories: Icon Clues?

Full credit to Zinc at the Smashboards for bringing this to my attention.

If you look at the address/filenames of various game series icons on the Dojo, you can see that each one is numbered. Now, looking at the icons we have seen so far...

01. Smash Bros.
04. Kirby
08. Pokemon
10. Mario
11. Yoshi
18. Kid Icarus

So, the number of the Kid Icarus symbol seems to indicate a minimum of 18 different series icons. We have 6 currently on the site, 4 more for characters confirmed in Brawl (Wario, Samus, Snake, and Fox). Additionally, there were 6 other icons in Melee (Donkey Kong, Ice Climber, F-Zero, Earthbound, Fire Emblem, and Mr. Game & Watch). So, at least, there are two brand new series in this game, barring any cuts of characters-with-their-own-series, or possibly the use of non-series symbols.

This could all mean nothing, but it's pretty interesting.
