i know we can have a head start this weekend, some are saying from tomorrow, if we pre-ordered and I wanted to know if you guys know when we can start installing it on steam. It's a fairly big download and I assume it will be a separate client from the beta so it will take a while from release before we can start playing. I haven't been on steam for long so I'm not sure how the whole preload thing works so any info would be appreciated. 
 
Thanks

I was wondering about the same thing, so I went to the Steam STO forums and asked there. Here's the topic I started there if you're interested:

I just get a feeling you launch the beta launcher and it will update.. has to be something like that since they haven't given any heads up.

Thanks for the info, that's great news about the client. Do we have a start time or is it just midnight(I presume central/pacific, meaning early morning for us across the pond.)

I heard 10am PST, it's not from confirmed Star Trek Online forum sources but many seem to be agreeing on that time.
