Bottom line. Anybody needing 2.0 can install it by hand, using CVS and using the PHP beta as mentioned here:
"However, DH has made a php5.3 build available as a beta. That means that if you want to run Moodle 2 you can select the php5.3 beta (a new panel option under Manage Domains->Web Options) , install Moodle using CVS (arguably a better idea if you want to stay current) and things should work just fine (DH will want to hear about any issues so that they can tweak their 5.3 beta to address any problems)"
Just did this myself, and it worked fine...
Only one warning that said:
"PHP Extension Intl. Extension is used to improve internationalization support, such as locale aware sorting. should be installed and enabled for best results"
