When the consumer product comes out is Oculus going to exchange all the dev kits for retail products? If not, then you just blew a grand$300.
Don't be silly. Of course they wont.
I didn't blow 300$ the consumer version will be lighter and have a slightly higher resolution. I'm not waiting a year for that. These are developer kits, which come with tools and bonuses the consumer one wont have.
Besides, I have plenty of money to spend.
