Crystal gave us the suicide storyline and the battle tower. Both of those are also features made after gold and silver, so once again no hiding of content
Emerald, played both ruby and sapphires storyline and was the perfect mix between the two. With the battle frontier, was most likely another feature that could only be developed after release.
So ultimately, its not like game freak was ever hiding features. In reality, the 3rd versions allowed them to put in new features that they were only able to develop AFTER the release of the main 2 games
