Haven't played as much of the new code yet, but impressed so far. Definitely an improvement, as I've finally had an actual Tag Team Championship match against the Legion of Doom. Some of the basic changes, like opening up the ramps for full orbits when not in an active match makes the game play so much faster! Some of the combos feel great when you get on a roll!
At least on the LE model, the spinning disc in the ring is frustrating. It tends to make it very difficult to intentionally hit the pinfall. The slammers are tricky to aim with anyway, and then when that disc catches the ball, it sucks all the momentum out and tends to pull it to the center more often than not. I think the spinner could be adjusted in a future update to enhance gameplay further. It's fun during multiball modes, and certain instances, but not when it's constantly running during an active match. Maybe short bursts would add some randomness instead of constantly running and becoming a vortex sucking the ball away from everywhere you want it to go.
The smaller updates like the audio quality improvement, and the lighting control and changes really add to the overall feel and help making the game feel more polished.
