It's WiiWare, so is downloadable...
As for the other Q, if it's sarcasm, then good, but if it isn't, or if other people are wondering then i have to explain:
1. The controller: It's gonna be the Wiimote sideways using the D-Pad and the 1 and 2 like they're A and B...
2. Graphics and Music: They resemble how the original Megaman games looked and sounded on the FAMICOM (NES) hardware, but it's not made for being emulated on the Virtual Console, it's made for the Wii Hardware, so it's gonna look & feel like the NES but without the NES hardware limitations and with a 50MB limit (No NES Megaman game ever passed the 600 KB wall and the Super NES X and classic ones the most they took was 2 to 3 MB).
But of course, we have to wait until more info is revealed...
