The original IoR wasn't explicitly tied into the original achetype progression other than not being able to get to level 10 on the island because you needed to go to a mentor in the city to do a short/easy quest to chose which class of the archetype you wanted. Similarly, in EQ2 the Gloomingdeep Mines (added many years after original launch) is limited to level 15 but designed to be until level 10. Island of Refuge was also intended for max level 10 even in the subsequent versions of it.
However, I do expect it will be IoR v2 rather than v1. I also expect the opening boat might not be part of the starting new character experience even though it had been somewhat (in a different version) added back into the game after it was taken out. There is a version IoR right now, along with a later version of the boat, on Live. That might be the version of IoR on Origins rather than v1, v2, or any other version they've had.
The current version is somewhat similar to the 2nd version but I don't think the 2nd version was specifically because of the change to the achetype to subclass progression but only because they were trying for a different type of "tutorial".
