Have you filled up your display case and emptied your bank account acquiring Nintendo's amiibo toys yet?  Hopefully there's still some room in both because the company has announced more of the NFC figurines are on the way with Wave 4 of the Super Smash Bros. line (here comes Ness, Pac-Man, and Wario among others) along with a new Super Mario line that offers fresh poses for Mario, Luigi, Princess Peach, Bowser, and Yoshi with only little Toad as the new character featured.  Characters are interchangeable with supported Wii U games so you can use your Super Mario Bowser in Super Smash Bros. for Wii U without hesitation.  The upcoming Mario Party 10 will include amiibo functionality although be warned that using Smash-compatible figurines with Party will wipe out your amiibo's Smash data and vice-versa.  Kotaku explains what you'll be able to do with the toys in Party:

Nintendo did say that Mario Party 10 will feature a new gameplay mode known as "Amiibo Party" in addition to the two that were previously announced. This mode works by putting you on a specific game board tailored to the amiibo that you're using, complete with character-specific abilities and traits. Mario Party 10 will be compatible with nine amiibos: Mario, Luigi, Toad, Peach, Bowser, Rosalina (and Luma!), Yoshi, Donkey Kong, and Wario.

Can the market sustain all of these products sent out in the market so quickly?  Is anyone buying these besides collectors and scalping middlemen?  As for me, I've decided only to pursue amiibo of my absolute top favorite characters in fun poses.  So far I'm holding at owning two of them (Mario and Kirby) with one upcoming release pre-ordered (Mega Man).  I'd buy Wario if he wore his traditional yellow and purple colors rather than his biker outfit.  The new Luigi figurine is tempting (his Smash pose is ridiculous and I won't stand for it sitting on my desk) and I have a soft spot for Ness after all EarthBound has done for me.  It would be a waste to own Captain Toad: Treasure Tracker and not get the Toad amiibo to go with it.  Hey, look, there's Pac-Man!

Uh oh.
