third strike was the best, but they've clearly stated that IV takes place right after II time-wise if I'm not mistaken. I'd also like to see those characters, but I think the new ones we'll get will suffice.
Also, who cares about destroying a brick wall? Seriously, is that going to take anything away from the game? Yeah it was fun..but I wouldn't be the least bit disappointed if it wasn't added. Then again, I don't play the game for fun, I play it for competition/multiplayer, so maybe that's why I don't care for it all that much.
Now, if only Hori made their joystick box in an octagon patern instead of a square (retarded design flaw), everything would be ok...
