Just want to give examples of MM's drumming outside DT, to make the point that he is not being more technical or drumming with less feel in DT. I think the following are excellent examples of MM's style.
The infamous Egg Zooming:

https://www.youtube.com/watch?v=N1-8j9zhdOEThose are pretty good displays of MM's drumming, and in a way, I would agree that those sounded different from how he played in DT so far. But I believe that the drumming approach is the same. If you listen to the songs, MM always plays musically in the context of the song, complementing what the other instruments are doing. It's the same approach that he brings with DT. He just sounded different because the songs are different. He plays to what the song is asking for.
If you slow down the Midnight Express drums, for example, it's quite similar to how he drummed Paradox of the Black Light in Illumination Theory. The way he played toms and cymbals in Fire Garden Suite, you can see some of that in The Enemy Inside, Behind the Veil, some parts of The Looking Glass, and the instrumental parts in Illumination Theory. For me, who has been following MM since I first heard him in Extreme, I got what I expected in DT12, which is him drumming musically in the context of the songs. I expect that he would continue to do so in DT 2015. If we want him to go batshit crazy, then there must be songs that would make him go batshit crazy in the context of the song (like the solo in Surrender to Reason).
