Is 11g ready for Production....?

We are considering upgrading our Enterprise Edition database from 10gR2 to 11g. My instinct tells me that its a bad idea to upgrade to the first release of a major version. I've been burnt in the past by upgrading to 9iR1 and 10gR1 (both of which I thought were useless). 11g has been out for a while now, is 11gR2 due to be released soon..?
