Lets not forget about Rand having 3 girls on the go!
I think the show-runner has already indicated that they'll be treating Rand's relationships differently... in that he'll only have one.
I reckon one of the key reasons why the series has been picked up is that it'll be able to show significant primary characters in both male and female roles - I understand the first season is very much seen from Moirane's POV, as opposed to other characters you might expect. Think it'll be written for as broad an audience as possible.
I'm looking forward to it - I'm currently listening to it on audiobook for the first time, having read it multiple times, and it being my favourite fantasy series - but I'm expecting it to either be quite poor, or it'll be pretty damn good but vary wildly from the core text. Which I'm totally fine about too. The books are much more of an
adventure story than GoT, and so to keep an adventure angle interesting over multiple series can be very difficult. But there will be an almighty void to fill post-GoT, however I'm not sure WoT has that little bit of realism (violence, sex, other adult-themes, etc.) that will appeal to the masses.
I'd rather they started making cheesing feature length films of Abercrombie's work
