they just did something to the PSN store to add more RPMs, things seem to be working smoother and I got my key redeemed and its downloading now - 179MB initial install, 150MB update, then launch that to get the actual 13 gig download
note: if you keep getting the error "this can only be opened by an authorized user" just wait a minute and try again it hasn't sync'd your PSN data yet
you must actually launch the ~200 meg destiny download to start downloading the full game after accepting the EULA, just getting the tiny PSN installed launcher IS NOT ENOUGH aka all you people at work without vitas are fucked
download is fast though I am chugging along at full LAN speed it seems, 5% done in under 30 secs
