I hate to see really good opinions (and dissents) go away after a case gets taken en banc. Especially in this case, which I briefly discussed here.
That said, (1) I'm not at all surprised that this one got taken en banc today-- it's an important (and close) issue, and (2) I have a keen sense that you'll see these same arguments -- and, assuming an appropriate draw, perhaps virtually the same opinions -- reappear after the en banc process concludes.
Stay tuned.
