Quoted from Rarehero:Everything on that playfield is from the movie marketting assets...the logos, the characters. The modes are all based on events in the movies.
This rumor is very interesting - on one hand a comic-based Spidey could be really, really cool! On the other hand - SM as it stands has a very engrossing sound package due to Willem Dafoe & Alfred Molina's clips and J.K. Simmons custom voices. I suppose they could keep the music, as it was all original anyway. If the voices were all new - we risk it sounding like X-Men. It would be very hard to go to a "Shittybeast" sound package on Spidey.
Anyway - this is an interesting rumor...let's see what happens. I could see myself re-buying Spidey if they knock it out of the park.
The PF art is the one minor knock i have against SM...if the PF art was redone in comic style it would be a perfect 10 IMO. I'd sell and re-buy one.
That being said...as you stated, the sound package is phenomenal as is. They couldn't re-use it. It would be hard to match it. They would also have to redo the animations and rework the modes too. And the toys would need to change since they are movie based.
It would be a big task to undertake and I don't see it happening.
