>According to the historical linguist, rather than reading: “Listen! We have heard of the might of the kings” the Old English of “Hwæt! We Gar-Dena in gear-dagum, þeod-cyninga, þrym gefrunon, hu ða æþelingas ellen fremedon!” should instead be understood as: “How we have heard of the might of the kings.”

So semantically... no difference.
