User blog comment:Xano2323/Colour Power in Sonic Lost World/@comment-4008402-20130603021433

I for one can't wait to see what colors powers are in store. It sounds like they'll be a little more complicated, with one using the touchscreen to control them.

Anyway, I imagine:
 * Some Wisps escaped to Earth/Mobius/Sonicplanet/Whatever when freed by Sonic, rather than stick around in case Sonic failed (don't stone me!)
 * Some decided not to return
 * Eggman hid some reserves of them back on Earth/Mobius/Sonicplanet/Whatever. This seems kinda likely, seeing as they're still in containment capsules. Eggman may not be the best evil genius when it comes to getting his plans to succeed, but he probably was brilliant enough to make some back-ups.

Another idea: What if the Deadly Six are connected the Wisps? Just a thought...
