The 432109 BTC that was at http://blockexplorer.com/a/8d7f1vDvvw
has mostly (~432078 of it) been moved to here http://blockexplorer.com/a/46bJajK7qK
at 2011-06-19 18:17:28 (UTC) (so post the massive sell off on MtGox)
Hard to imagine there is no connection with today's selloff.
block 130281 was last Sunday (2011-06-12 12:57:20) - Japan is +9 hours from UTC, so @21:57 Sunday night in Japan.
Today's movement was at 03:17 Monday morning in Japan.
Is MtGox being targeted when it's likely there is no one there?
