"Although the DK2 boasts some impressive specs (and a high price to match), Oculus Rift has not yet given any indication how it will measure up to the consumer version. The consumer version of the Oculus Rift also has no set release date or price yet."Yes they have, in several different places. They have said that the consumer version will be a step up from DK2. Consumers will want to wait.
How is $350 considered expensive exactly? Compared to liscence fees, workstation computers, payroll/overhead, software... heck, even a standard workstation monitor will set you back almost $1K.$350 seems like a very justifiable price point, and if the final retail release is in that price range then I'll throw some money at it. Probably the coolest experience you can buy for under $500.
