I'm interested in picking up the WiiU version, although I don't have a WiiU so that might make it a bit trickier.
I'm also not really thinking of buying a new console soon due to saving for a wedding ... but dammit I want new smash bros. I love these games so hard.
You have any idea if they added a stage builder this time around? It might not be on the 3Ds version anyway, that doesn't necessarily mean it won't be on the WiiU version. But I really loved that function and hope it's improved upon with Smash Bros 4.
