Regarding Topre, 'mushy' to one person is 'nicely damped' to another! I've had my Realforce for less than a week, but I love it. It definitely lacks the tactile excitement and presence of some of the Cherry switches (those that I've tried), but to me it has an understated, damped feel that gets out of the user's way. I could see how some would call that mushy, but to me it feels like a professional, precision tool. To each their own!
To the OP, the Filco-like, upcoming, TKL board that I'm waiting for is the Leopold FC700R.
