As someone with vision problems, this part from the review kinda left a sour taste in my mouth:
"These legends are smaller throughout, which may be the company accepting feedback that the previous legends were too large for many."
I don't know about others but, the large legends/font was one of the main reasons I went with the K68 as my first mechanical keyboard. Because it was large enough for me to see comfortably (didn't have to get real close or strain my eyes). Not to mention large font boards are rare, especially in the PC gaming community. Sad to see Corsair going the same direction everyone else is going.
Now, keep in mind, the font on my current board from HyperX is a "normal" size - not too big/thick or small/thin (Razer is good for the latter) -- and sometimes I find myself hitting the wrong key when typing, but the size of the font is balanced out by the fact that I got HyperX crazy vibrant pudding keycaps on this board, and because they let in so much light, my eyes don't get fatigued as much.
