This article is a look at the actual hardware, and it says that as the console will make a bigger effort to display the 3D, the graphics won't be as good in ACTUAL games.
I've seen plenty of PSP games that I consider a lot less eye-popping than the Kid Icarus reel, both MegaMan titles among them. Then of course there is the Metal Gear Solid demo we saw; even if it wasn't gameplay, it was realtime. And it looked freaking awesome. I don't expect every dev will be encouraged to push the 3DS hardware to its fullest (just look at the Wii), but it seems capable enough to me.
I'd imagine the effort to display a 3D effect in a polygon game is probably comparable to doing 2-player split screen: Programming-wise, if you're already working on a 3D plane, then it's just a matter of showing two different camera angles.
"can't duck or shoot up" gameplay
Get equipped with: Model FX.
Yeah, ducking hasn't gotten much fanfare beyond X5/X6, but lots of MegaMan games including nearly all of Inticreates' have some means of multi-directional attack (all Rod weapons in the Zero-series, Model F/FX in ZX series, Bass in MM&B/MM10, and Axl in X8).
Megaman 9 (still the best, IMO)
The power of an 8-bit can of paint is truly amazing. I for one do not believe 9 comes close to equaling the quality of actual NES games. 10 did better, though, if only there was some way to turn off that damn B trigger weapon switch. You might want to consider a Classic controller for that.
