To those who've pre-ordered/pre-purchased Guild Wars 2, you should start downloading the client now and keep it updated before the early start. See this thread on how to do that (near the bottom).
If you've been participating in the beta events and you still have the files, then you can spare yourselves another 16 gigabyte download by just copying the dat file over. First run the downloaded Gw2Setup.exe and wait until it starts downloading 216k+ files. Close the client at that point and copy over the beta dat file to where you installed the GW2 client. Afterwards, run the GW2 client again just to make sure everything's okay. Just keep it up to date between now and the early start and you should be good to go.
