  We present and analyze a new M' detection of the young exoplanet beta
Pictoris b from 2008 VLT/NaCo data at a separation of ~ 4 AU and a high
signal-to-noise rereduction of L' data taken in December 2009. Based on our
orbital analysis, the planet's orbit is viewed almost perfectly edge-on (i ~ 89
degrees) and has a Saturn-like semimajor axis of 9.50 (+3.93, -1.7) AU.
Intriguingly, the planet's orbit is aligned with the major axis of the outer
disk (Omega ~ 31 degrees) but probably misaligned with the warp/inclined disk
at 80 AU often cited as a signpost for the planet's existence. Our results
motivate new studies to clarify how $\beta$ Pic b sculpts debris disk
structures and whether a second planet is required to explain the warp/inclined
disk.
