I just got an email from the Pycon interest mailing list by Guido van Rossum. Here are some details on pricing:
- $150 early bird (registered and paid up to 4 weeks before the conference)
- $200 regular pre-registration (registered and paid up to a few days before the conference)
- $250 all on-site payment (pre-registration is still strongly recommended when paying on-site, to ensure your space and to speed up badge creation)
There is also an IRC channel on irc.freenode.net called #pycon.
