Update (4/8/2014 @ 8:48 PM EDT): Some commenters pointed out that the K70 already exists and has been on sale for quite some time. That is true, however Corsair has refreshed the line, apparently adding Cherry MX Blue and Brown along with the "original MX Red". It is a new product that will be released mid-April.
No, this is not the Cherry MX RGB keyboard; we still do not know when that will come out. The K70 is a mechanical keyboard made out of blackened (anodized) aluminum with red backlights in each keycap. It comes in either Cherry MX Blue, Red, or Brown. Unlike some of their previous models, every key is mechanical. It is advertised as "100% anti-ghosted with full n-key rollover". Being a USB keyboard, it is unclear whether it actually allows every key to be pressed simultaneously or whether it is limited by the interface.
That said, previous Corsair keyboards registered as 3 USB devices and split inputs between the three to overcome 6KRO limits, thus allowing for 18-key rollover. This should be sufficient for all quadridextrous typists. For the mental image of someone typing with their eight fingers, two thumbs, and all but two of their ten toes, you are welcome.
Also, and I have said this before, but it kills me when a keyboard based on an NKRO key matrix (even if it is limited by USB) needs to describe itself as "Anti-ghosting". Anti-ghosting is a hack which prevents unintended keypresses by locking-out the keyboard when it gets confused. Many keyboards, to save money, group keys together in their grid of circuits. Basically, each key is assigned to two circuits and the keyboard can thus see which switches are pressed by their pairings. The keyboard does not know how many switches are open on each circuit, just that at least one is. Ghosting occurs when three or more keypresses cause the same signals as four or more keys. The keyboard then has two options: register all possible keypresses or jam and ignore everything (anti-ghosting). An NKRO-based matrix uses diodes to further isolate keys so that each can be individually addressed.
Thus an NKRO keyboard never needs to jam. It is immune to the conditions. Unfortunately, if they did not advertise anti-ghosting, the uninformed will think it is an inferior keyboard... rather than so superior that it is immune to the problem in the first place.
Back on the Vengeance K70, it will be available this month for $129.99 USD (MSRP).
