Where in the press release does it say it's the Mega Drive version of SSFII? The Official Nintendo Magazine pits it as an update to the already released SNES version.

what happened to muscle march?

posting here aswell:

It's a bit "buggy", they've changed the range when you pop the bubbles, without compensating the levels, so you can get stuck in narrow spaces, like on level 99, and plenty others. The bubbles pop as soon as you touch them, so it's impossible to blow any in spaces that are 2 "squares" wide. One other bug is that you no longer can blow bubbles through narrow spaces, one square high, also unbalancing some of the levels.

According to the swedish Nintendo site new games will be added every second friday.

So I'm guessing that 20:th is the first batch, then 30:th, with the next one after that at the 13:th of june
