If you want to aim, Axl is your man(boy?).
If ZX3 has Model A(xl) and ducking in an ability, would you get it?
If ZX3 has the gameplay of Metal Slug, Gunstar Heroes or Contra, I'll get it.
Litmus test: What kind of performance drop do you see when a GCN game is running in split-screen? 3D in a polygon game is a simple matter of displaying two different camera angles.
That said, 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.
Get equipped with: Model FX.
As I've said, seeing as there are tons of different opinions and analyses, we'll just have to wait and see.
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).
I don't want models or powerups that give me basic things. I want a game with an actual GAMEPLAY that lets me do crazy [parasitic bomb] and gives me more freedom. Megaman's a dude with a gun in his hand. He should be able to move better.
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.
I actually liked 9 ALOT, more than any of the NES titles, while 10 just seemed like it had much worse level design. 9 seemed... intuitive. Easier. Not frustrating. Things 8-bit Megaman games usually aren't.
