1920x1080 60p cameras are rare.
If you're willing to work with a large sensor camera the Sony FS100 does 1080p60 at about $5k without lens.

HD mode
PS (28Mbps) 1920x1080 60p
BTW for those wondering, Sony F3 does not do this.
1080p60 is not really a standard (at least as of yet) so even the post workflow can have some kinks.
