Graham Scheper has a recent video on this topic. He also believes that "Hwaet" is not an interjection, but more like Red Riding Hood's "What big eyes you have!"
I watched this video a few days ago after it was randomly recommended by YouTube. Definitely found it very interesting and he has a load of other videos about learning Old English, so I'll be checking out more of them soon.
