Yup, seems like he's telling the truth. Three Mystery Dungeon games released in a gap of three years, three Ranger games released in a gap of five years, four Original RPG games released in a gap of four years, and they're the same!
Thank goodness Zorua and Zororark opened my eyes to it: HeartGold will be the last Pokémon game I buy, because I know the V Generation games won't be ANY different from DPt. The problem is that Pokémon still sells well because of its appeal to stupid kids watching the most ignorant character ever: Ash Ketchum; as well for long-time fans who are fooled (like I was many times) thinking the next game is a revolution (Wi-Fi Plaza? Battle Frontier "2.0"? Pokéathlon? I don't bite that...).
The main problem of Game Freak is that they are way too afraid of innovating. Nintendo innovates in every game the EAD develops (with few exceptions), while Game Freak and third-parties (Chunsoft for PMD, Genius Sonority for the console games) don't try it at all. Not that I want radical changes in the battle system, but innovating in story, exploration and training is what could make the series worth of recognition.
What I mean it that, for instance, if you ask a Nintendo fan if God of War or Halo is really that worth of being called "great franchises", it's most likely he or she will agree (even with some hesitation some times); on the other hand, if you ask a Sony/Microsoft fan (not a fanboy!) if Pokémon deserves the same, he or she will probably say no, because, for them, it lacks "quality".
The series is big in sales, but low in scores and consensus in the video game society, and what is responsible for this is the total lack of renovation on it. I have to agree it's the same thing every time: get a Pokédex, defeat the evil organization, achieve the eight badges and defeat the Elite 4, catch'em all [and defeat the Frontier Brains when possible], with a few features that eludes any gamer unable to stop his or her impulsion and reflect about what that game will bring more than the last's (and I mean what REALLY makes the difference).
Everyone who is amazed by these two new Pokémon (who look more like a "Diamond/Jade" Telefang), I ask you to stop with the euphoria and, at least, wait for technical news from the games, to see what will bring besides what we've been seeing in the last 14 years.
