Ah okay thanks. Do you think Razer owners will be a big enough demographic for the new profile to justify the 6.5u key on it's own?
Hold on a minute. Razer BlackWidow and Huntsman have 6u space bars. They are not 6.5u.
There are however several other
gaming brands that do use 6.5u space bars. For instance, Corsair.
Razer BlackWidow and other modern keyboards have a centred stem.
Some older Cherry keyboards in the G80 series have
an off-centred stem however. It should be possible to support both: The Cherry-compatible key stem will clear the centred switch on the BlackWidow.
Some (if not all) Razer keyboards with 6u do have the
stabiliser stems farther apart than others though. I am not sure about the Huntsman's measurements, but I know that at least older Razer BlackWidow do have stabiliser stems wider apart but they do use Costar-style stabilisers, so it might not matter that much.
While Razer BlackWidow is a very popular keyboard, I think that is primarily because of availability: as it has been widely available in retail, and an
entry into mechanical keyboards for many people. Once they are in, they may want to buy a better one. Putting high-quality keycaps on a Razer keyboard (with wide stabilisers) would be like putting lipstick on a pig IMHO.
If you see something that is glaringly messed up, please let me know.
When the Space Bar is 6u then there are
two 1u modifier keys in-between right Alt and right Control.
These are often Windows+Menu, Windows+Fn, Fn+Menu or Windows+Compose.
