She mentioned that there was a love triangle between the three for the next book. Emma Watson was inteviewed for this, and the question was: "Rowling has informed us of a love triangle between the famous trio in future books; do you have feelings for Dan Radcliffe or Rupert Grint?"
Her answer was no, but this was like, before the second film. I vote Dan and Emma all the way! Hoo-ahh!!
If you read through all the books carefully, you see little shreds of evidence that Hermione likes Harry, and Ron likes Hermione. Kinda. And Harry doesn't know who he likes. Would you like a 10000 word essay on evidence of Harry/Hermione?
