Linking HOM from GW to GW2

Ok.. so I have two Guild Wars accounts linked to my NCsoft account. These are two separate GW logins, and the HOM calculator shows them as separate.

Now, the question is. When GW2 goes live, will I be able to split them to two separate NCsoft accounts? I realize you can't split GW1 accounts off, and I'm not asking that. I'm trying to get the S.O. involved (significant other.. ) and would hate to do all the work to get a full HoM and not be able to let her use it.

I've looked all in multiple places, and haven't seen a definitive answer. I'd hate to send Anet email on something this trivial so I hope someone has a pointer to some good information.

Thanks all.

Short answer is: we don't know yet how the accounts are linked. ANet/NCSoft won't tell us until they're ready.

It makes logical sense that 1 GW account can link to 1 GW2 account, how it will be done is not yet clear, it could be done by putting in your account details, or by using your NCSoft account to link them.
If it is done through NCSoft then it is possible to have multiple GW accounts in your NCSoft account so then one would have to be selected. It isn't impossible to have multiple ones but I would find it surprising.
