Yes you do, I just didn't explain it properly.
fontspec uses XeTeX's /B and /I font suffices to load fonts
for \textit and \textbf.

This whole thread is pretty much the reasoning behind the most recent
fontspec's \newfontface command -- for when you want to
load a font without associated italic/bold shapes.

Don't let Peter confuse you. The original poster's email demonstrated
that "{\textit{Italic \textit{Italic Too}}}" behaves *correctly* for
   "\fontspec{Myriad Pro}"

But in his example (simplified)
   "\fontspec{Myriad Pro Italic} Italic \textit{Surely this should be  
Italic too?}"
it's the automatically found "italic" shape of "Myriad Pro Italic"
(which doesn't make sense) that is returning the font to upright.
(In a perverse way, the italic shape of a slanted font could in argument
be claimed to be an upright one.)

But the behaviour of the /I suffix is nothing to do with me :)
