I definitely would like to get my hands on rF2. As someone who plans on building a track for it, it'll be nice to get my hands on the tools--see what what we'll need to be adding, play around with the (hopefully) new shaders, seeing the track in the new lighting system, etc. Which, seems to me, from what they've already said, is the major purpose of the open beta. They've already run the closed beta with the larger mod groups / licensed developers; now they're opening it up to the rest of us, but from the impression they give, it's still not ready to call it 'finished' (even as a first pass).
It just doesn't make sense to me for anyone to say "they shouldn't release the open beta yet". It's a choice, not a requirement, y'know. If you can wait, then go ahead and wait. If you don't feel it's 'ready' to play, then don't play it. They've already said a free demo will be available at or closer to the full release. Odds are, unless you're actually going to be creating content, you're not their target audience for the open beta, anyway (with the exception of maybe testing the matchmaking service under a larger load). So, unless you guys want to play just the content that comes with the game (nothing at all wrong with that) for 6-12 months after the full release, keep quiet and don't give ISI the wrong idea--we want rF2 sooner than later .
However, I will say to the devs that I'm very much aware that the time between Beta and Gold is high-pressure, go-time. So, definitely enjoy the much-deserved holidays and come back refreshed and ready to go!
