Okay, obviously we’re talking about The Beatles: Rock Band, which released just over a week ago, and which features some crazy specialized instrument add-ons, like Paul’s signature Hofner bass and Ringo’s branded drum kit. Not coincidentally, the game also launched in conjuction with remastered reissues of the band’s catalogue — which, here in the office, we’re pretty stoked on.  Of course, $250 retail (the cost of the 13-part box set) is a lot of dough to spend on tunes you’ve pretty much heard before — especially when paired with all the Rock Band packages — so for any fan to get in on the action, they’re looking at a hefty financial commitment.

As a result — and you know what we’re gonna say — eBay sales have gone through the roof.

… and that’s just any listing with the keyword “Beatles” in it!

If total amounts aren’t your thing (fair, considering the new release factor), consider this: in the two weeks leading up to release date, sell-through also shot from 38% to 51%,  while bids per listing nearly doubled. And if holiday patterns are any indication… well, that’s only the beginning.

Terapeak’s Hot Media charts for September won’t come out for another couple weeks, but do you remember the following from a couple months back?

… Okay, we still can’t get over how unbelievable that is. Jaw-dropping. Inconceivable.

But don’t be surprised to see some kind of Beatles “lite” version as holiday sales pick up…
