Final
These early screens were featured in a preview in issue 55 of Electronic Gaming Monthly. They show the the spirit gauge looked different. You can also see that King's spirit gauge has changed from green to orange in the screenshot, in the final version it'd still be green with that much left.

I also don't think John can do that kick in the final game.

Final
Temjin's stage looked quite different in the preview, with it being set at a different time of day. The truck had different colors and some of the crowd were different. There's also some different scenery in the distance.

Final
Eiji's stage looks similar to the final version, but you can see a plane in the background is facing the other way and the vehicle in front of it is also different. The buildings in the background are also different.

Eiji is performing his zantetsu ha super move. In the preview, the sprite for this projectile looks bigger, and Eiji's hands are also different.

Final
Yuri's stage was at one point completely different, whilst it was still set in a gym, it looks nothing like the final version. Also of note is that even though the timer is at zero, Yuri isn't in her time over loss animation, something that would have happened in the final version.
