a pinsider went to the recent pinball show and saw a presentation by David Thiel who did the sound for X-Men said this

"I watched the David Thiel interview last night and there was some new information in it.

* He mentioned having 9 villains and 9 heroes, each with their own mode and music. (Confirms what we've heard, and is almost more than is represented by inserts.)
* Mentioned wizard modes, plural.
* He referenced many times that the "young guys" had lead on the code with support by both Lonnie and Lyman, primarily Lonnie, and that they were big fanboys and focused on authenticity.
* He personally watched like 40 hours of XM movies and animated shows, plus read lots of comics, so he could get it right.
* He used putting Lady Deathstrike together as an example of a character that needed research -- interesting because she's got no insert, is more of a Wolvie villain, and I don't think is even on any of the cabs."
