About Cherry MX Ultra Low Profile on Alienware Keyboards

Hi, so I had a few questions about the ultra low profile keyboard on the Alienware Laptops. First, does anybody know what the latency on them is? Also, I doubt anybody would know the answer to this new question, but I figured I might as well put this question about there anyway. Is Cherry MX in the works of developing a Linear version of the Ultra-Low Profile switch. Right now they only have the Click version, but I was just curious if a linear switch would ever become a possibility in those regards. Thanks!
