A serious one.
Is there any evidence that states the PS2 interface is on it's way out as more and more keyboard/mice manufacturers opt for USB?
TBH, I can't remember the last time I saw or used a PS2 mouse or keyboard. It must be over a year. I'd say it was on the way out.
Funnily enough, Logitech here also. They do make some excellent stuff. G15 keyboard and I think I'll be replacing my Raptor M2 with a Logitech soon - the Raptor would be a very nice mouse, but the build quality has turned out to be poor.
