I looked back into this since it was a while since this was a raging issue (which is why I was looking for confirmation in my post. Here's a link to a BB-Charles post from over a year ago on this topic:
(110085.4)This explains why I had stuck in my head that salaries were higher for foreigners in addition to the increased merchandise sales for national players, while it's only the merchandising change that actually happened.
Anyway, I really don't think BB will model itself on European models that set a ceiling on the number of foreign players. Teams from countries with fewer leagues will complain that they are at a disadvantage compared to the countries with more leagues (like Italia, USA, Espana, etc.) since they would have a much smaller pool of free agents to choose from to fill out their rosters, and that would drive up the the transfer costs locally for them. (I personally don't have a problem with that based on the way the BB economy is structured, but that's a discussion for a different thread, and a conversation that's happened in many many posts in the past.) Furthermore, I believe that the BB transfer market philosophy is one that prefers as open an market as possible, but that's not really for me to say.
