I guess I'll answer this again, as I had a chat on related matters with the people at Patek before buying this watch earlier this summer, but Volker please feel free to chime in if you want to add something.
Initially, I also considered this move by Patek rather unusual -- listing the 5088/100P as a "Limited Edition" (see my picture below from the 2015 Rare Handcraft book), and then keeping the reference for a few years in the regular catalog as well. This is why before deciding to go ahead and purchase this model (I was sent it to view as a surprise in May and pulled the trigger over a month later), I wanted to better understand the actual production numbers. I'm not going to disclose them publicly, but as I said earlier, I can tell you that total production has in fact been *much* more limited than people may think -- making a 5088 *a lot* more exclusive, for instance, than an enamel Worldtimer, though of course much more accessible than the out-of-catalog Rare Handcrafts, which can often be counted on one hand.
Italy, which is a pretty decent market, didn't get on average more than one 5088 per year, while other world markets *never* saw one. A member mentioned earlier, which I didn't know, that the London Salon also received about one 5088 a year for its clients. In general, total production has been less than several recent "Limited Editions of xxx units," and the reference is likely to be discontinued soon. So I guess the issue revolves more around the *definition* of a limited edition, rather than its concept or translation into numbers. And for Patek, limited edition (with NO specified number of units) really only means that -- the watch will be produced in "small" numbers. Note that this does *not* even imply production is limited to one year only -- not many people know this is the case even for the out-of-catalog Rare Handcrafts, where it's not uncommon for the 4 or 6 units of a given reference to be released over the span of 2 or 3 years! ;-)
Therefore, once production of the 5088 is factually limited but Patek decides to extend it over the stretch of a few years, wouldn't it make more sense to just add the two words "limited edition" next its listing, so that nobody will raise any questions? Perhaps it would be easier, but it's generally inconsistent with how regular catalogs are presented (this is not even done for a 6002, or 6300, 6301, etc., which are *much* more limited than a 5088! ;-)
Hope this brief reply can reassure you about the transparency of Patek's production of this reference, as much as it reassured me before accepting the watch!

Cheers.
