Not wanting to affirm a known scammer, but I just sold this corpse to them for 1.2B as you can see in my thread below.
This is a legit corpse, though if you want to buy it, you should use a trusted third party like Elizabeth Norn and NOT use trade windows which is a trademark scam of Serenity Fireslayer.
However, I can confirm I was in Otoh on this day during GM week and I witnessed both the destruction of the Cerberus and capsule and I scooped the corpse on that day.
For interest, Bjornbee was FC for the Gamesmasters on that day.
Nah 1b-2b is about par for the course, and Ill offer 2b.
Its the most ive paid for any one corpse, including CCPs, most major FCs and corp/alliance leaders. The problem is that its a collectors item that really has no way of being shown off, unlike a ship, mod or skin. The people that pay the most are those who have a place to put them.
