And I wish I wasn't so pessimistic, but given what we saw throughout 3e's run (and still see from some critics), I think it's inevitable.
Ahh, but this time around it (might) be a good thing, no?
If the CharOppers get a hold of a beta version and then mangle it into an unrecognisable, heaping pile of molten goo, and then hand it back to the designers and say, "Umm... we found a few flaws... and it imploded..." then maybe those flaws/holes can be fixed before release?
