I would be interested in buying if mechanical version is made. However, I don't know if we should contact Razer to make them. When I got warranty service for my n52te, the Belkin was the one who I had to contact.
I have n52te and I think it is pretty comfortable. I bound keys to mouse buttons and navigation keys (Up, Down, PgUp, PgDn, Home, End) and mainly used it when web-browsing. The placement of scroll wheel and ability to map the wheels to something else is also nice.
One thing I love most about n52te is that it has on-board memory and that extra software is not required once you customize your settings. I do a lot of work in remote desktop environment, and in that environment software bound keys are useless. (I also own G13 and it also has on-board memory, but the memory is only used to store settings. So, in order to use customized layout, you would require software to be installed. It is close to useless in my working environment. It works fine once software is installed though.)
However, I think many people dislike on-board memory. Or should I say, many people have complaints about the limitation from using hard-ware bound keys. When I google n52te, I see people complaining the previous software was much better. Well software implementation is much more flexible, hence it would be generally better. However, one catch about software implementation is that you should have admin privileges on all of the system you use the board so that you could install the software. Also, you can only use them under specific OS for which software is available. If you are using Linux, you can use n52te once you customize the layouts, but you cannot use old version.
Well, my wish to make mechanical version of n52te with on-board memory and with hard-ware remapping. I would love to see a keyboard with flexible hard-ware remapping with multi-layered layouts.
