Yep, that's the quote! Good find, San. I remembered that it was meant to be a form of foreshadowing or something along those lines... Time to speculate.
If it is the "Staff of Moses" now known as "Staff of Kings", guessing it's the same staff.... now what MacGuffins are related to that? Ark. Staff of Aaron. Anything else?
Another thing: Would Abner have researched into that too? I mean, it is connected to the Ark. So Marion could be in this game... wait a sec, I also remember a quote to do with familiar characters that could be appearing in this game. They never said who, but they said there would be characters from the films involved in the game's story! Hmmm...
