There's been very few (any?) bugs reported against beta1, so it could potentially be Real Soon Now. If forced to guess, I'd say mid-November, but of course the real answer is "when it's ready". There's also talk of an in-place upgrade tool for 8.1 to 8.2. In any case, you'll be much, much happier if you do this project on at least 8.1.x, as 7.4 is pretty long in the tooth. Due to Red Hat's support requirements it will probably remain supported for a few more years by Tom/the community, but you might start having issues getting commercial support.
