The game is being completely remade with polygonal awesomeness though, yeah? ...Unless you mean by the only exclusive content being the 3D effect, is that this game is also being released on other platforms, in which case I'll proceed to have a cry about it. $2 on iPhone? Piss off. >_>
I've not touched the Nintendo downloadable versions but have blown through the freeware version a couple of times. I'll have no problem paying for this, considering I'm an importer and am already saving butt-tonnes of money anyway. Not such a huge deal taking slight risks, ya know? Let's hug!
*Edit*
I should also mention that I've yet to play the downloadable versions due to the fact that our release schedules 'ere in Aus are screwed. No Shantae for us, no sirree! But hey, in May, that should all change, given that I went the import route this time. *Flips of Nintendo of Australia* The entire US DSiWare at my fingertips! ... ...So, just Shantae then?
