Actually this bit of APS marketing is somewhat misleading (as is most
of the rest of APS marketing, and probably all marketing). (Have I
made enough unsubstantiated generalities yet? :)

APS cameras achieve different formats by cropping the frame.  The
landscape, portrait and normal formats all use the same size frame of
film and simply mark cropping instructinos on the magnetic strip.  You
can do similar cropping with 35mm film (or any other film format).

True panoramic cameras use different frame sizes to achieve panoramic
results.  For example, in 120 format (where normal cameras at 6x4.5,
6x6 or 6x7) panoramic cameras are 6x12 or 6x17.  In large format
(where 4x5 is currently the most popular format) modern panoramic
cameras are 4x10, which is often achieved by cropping an 8x10 exposure
(because only three companies currently make 4x10 cameras (with two
incompatible holders) and no one make 4x10 film).
