But those are some damn good batteries!

If that's the case, and microsoft paid 100 million, where is my cut of the money?

How did they spend so much and its the controller that's the most like its predessor. 

Ms just loves to throw out how much cash they spent on stuff. Like it matters.They remind me of those kids in high school that paid way to much for shoes and used the price to declare they are better than yours.

Cool, best controller ever + $100m = even best-er controller?

$100 million and they couldn't find a way to include rechargeable batteries for $60...

Somebody wore Jordache in high school...

Maybe that's part of the cost?

100million in 2.5 years seems reasonable to me. Thats just 1 dollars development cost per controller or even less. Money well spent imo.

100 millions dollars of research and yet runs on battery =')

Nice played MS
