Capcom has responded to the concerns about Ken's Medium Dragon Punch in SSF2T HD Remix being overpowered. They had this to say.
As some of you might have noticed, there are some Ken shenanigans going on related to his MP Shoryuken. Basically, it's a monster and threatens to shape the world of SF as a whole. This issue was realized after the beta was approved and has since then been changed so that the MP Shoryuken does not juggle like it does now.
Hopefully that quells anyone's fears, or stifle's a certain persons hilarious laugh, that the Remixed mode will be the best that it can be. If you haven't noticed anything wrong with the move, then keep on moving, there's nothing to see here.
If you're really worried about game breaking issues making it into the final release of Super Street Fighter 2 HD remix, keep in mind Capcom has a great reputation for balancing their games.
While they're certainly not perfect, they don't typically leave in blatantly game breaking moves in the final release. They do so much testing, and they've got a great team behind this -- so don't worry about it too much. Just look at their track record.
