The iso method is an extremely inefficient method to deliver a mmo game client. This is because every patch, a whole new iso file would need to be made that includes that patch, and the WHOLE iso would need to be downloaded again (many gigabytes) and then installed over itself.
It is much more likely (as others have said) that a small "patcher" program will be downloaded. 20mb or so.
The patcher then downloads the rest of the game, and also provides the updates to the game. (this is how WoW, SC2, D3, FFXI, FFXIV 1.0, and many other MMOs do it)
Even new WoW disks only have a single 5mb file on them. The patcher. They contain no actual game data.
I checked my Starcraft 2 disk, it also had only the patcher on it. 15mb or something. Just used to download the game from the web..

Some companies will include the base client, and the patcher on the retail disk. This saves a good portion of downloading to begin with. Only the updates need to be applied after the base is installed.
For the retail version disk, expect to see the base release client + patcher on the disk,
For the beta, and for release, expect just a patcher for us legacy members.
