Update or Download?

Are we going to need to download the game prior to launch or will a simple update of the beta client work?  Anyone know?

Pretty sure they said upate the beta client.  I recall reading on ESO's webpage that you should not delete Beta client.

I read that the Beta client will continue to work when the game goes live.  Our beta test toons, however, will be deleted prior to game going live.

8 more days to early access...  HAH :)

The official ESO support page confirms that we can use the beta and patch up for live:

Can I use the Beta client for the release version?
Yes. Players do not have to reinstall the game client when The Elder Scrolls Online officially launches. They simply need to patch the client using the ESO launcher.
