I seams they have a really ... new, approach to launching from their site you can read this
'For the first release we have decided to focus only on a few starting races and classes so that we can refine each to be unique and expansive far beyond what other MMOGs have to offer'
Seeing that they only have notes regarding the human race and the main classes "healer, soldier, ranger and magus' (read as priest, warrior, ranger and mage class types) it seams likely that these will be the starting race / class combos. They also seam to bee using the Eric Cartman marketing strategy http://www.southparkstudios.com/clips/152804 with the announcement of a 'Controlled Release' when Alganon Launches, only a certain number of new subscription keys will be created each month.
