Staffordshire Hoard Origins

I was talking about the Staffordshire Hoard in class yesterday, when the subject of its origins came up. I had previously heard two, opposing theories:

1. That the hoard had been stripped from the losers' weapons by the winners. This seems pretty plausible, until you ask the question -- wait, the winners lost a huge hoard of gold and silver and didn't go back to find it? Surely the hoard would have been too heavy and bulky for just one guy to carry, so several guys lost it?
2. That the hoard had been stripped from the losers' weapons and buried for safekeeping by the losers themselves, but everyone who knew where it was died in the battle. Again, plausible, but I'm trying to imagine a scenario in which you're in the middle of a battle, losing, then take a time-out to strip your weapon and bury the appointments.

After class, though, I realized that I heard these two theories in the fall -- in other words, shortly after the Hoard's discovery. These weren't fully-developed ideas; they were probably just barely beyond the point of speculation, whipped up on the fly.

Now that a year has passed and specialists have had time to examine and discuss the Hoard a bit more carefully, has some sort of consensus been reached as to the Hoard's origins? Have either of the above explanations been further developed, or has some third explanation perhaps emerged?
