It must be seasonal changes, as you mentioned. The most expensive Prada nylon bag I have, from the so-called "couture" collection, uses Lampo, but then I have one from the sport collection (NOT the red-striped line), priced about half as much, that uses Riri.
Of course, Prada changes their quality/materials/locations all the time and so really you never know what you're getting. This past year, I received a gift of a travel bag and it uses cheap, no-name zippers that will probably fall off in another year or two. As well, the materials were so much crappier than my older bags that I actually took it to the Prada Store, thinking it was a fake. "No, not a fake," they told me, "just from the 'entry-level' collection." I think this is Prada's euphemistic way of saying, "We've just really lowered our standards while raising our prices."
Checking around the closet some more, I have some YSL Rive Gauche jackets that use Riri as well; some Prada jackets, Gianni Versace Couture (made by Zegna), and Lardini (the suitmaker that makes Dolce&Gabbana) that use OPTI zippers for the pants.
Edited later to add: I just checked and I made a mistake. The Prada bag I thought was Riri was actually IPI, the OTHER brand that Prada uses (they use Riri, Lampo, Ipi, and then some no-namers). My mistake! Anyway, IPI are also fairly decent zippers.
