Only caches of german sites are left, but Logitech looks to be launching a "G810 Orion Spectrum" keyboard soon.
Judging from the tiny photo, it appears to be a more compact wired keyboard as compared to the G910, with no G keys on the left or top. According to descriptions, it uses Romer-G switches, and all keys are RGB illuminated. I don't quite believe the price though -- 189 euro is the same as the G910, which from the surface appears to have more functionality. We shall see what else the G810 brings to the table.
