Capcom has just announced the Mega Man Zero Collection, which is a compilation of all four Game Boy Advance games in the Zero series.

Mega Man Zero was first released back in 2002 and praised for going back to the franchise's original 2D platforming roots. The Zero Collection will be released on the Nintendo DS on April 22 in Japan and priced at ¥4,190 (US$$46).

No word yet on whether this is a "port" or "upgrade" with new visuals and audio.
