Er, honestly, while I do think as a factor in the canon series H/G is just as, if not more important than R/Hr by fact that Harry is, indeed, the protagonist, I kind of have to say that I saw the inevitability of R/Hr far sooner than I did H/G - while the feelings the two Weasleys had for the others was pretty clear since CoS, I kind of felt like Ron's behavior toward Hermione was more indicative than Ginny's toward Harry, I think it was more subtle than 'Ron has a crush on Hermione.'

And Hermione has always been my favorite character - which I know is sometimes an oddity among the R/Hr-Ron-Weasley lovers (Ron could annoy the crap out of me early on), but that probably did mean I was always more interested in her love live than even Harry's.
