A Q&A with BF3 Global Community Manager Daniel Matros (zh1nt0) on a public teamspeak with the German community, and details of the discussion from the EAUK Forums have exposed some new unconfirmed details regarding Battlefield 3 and the release of the BF3 Beta next week on September 29th.
Here's a snippet:

Between 2-3 gig beta client.
You can not UPDATE alpha client you need to re-download the new Beta Client.
Netcode is totally rewritten and new.
No level limit @ beta.
Cant join as a Squad if the Team is full so battlelog groups won’t get split.
