Fifth Generation is a must. Frankly, I don't see why Nintendo would stop creating Pokemon and games with new Regions. Pokemon Fandom still isn't anywhere near a downfall. Diamond and Pearl might have been a slip down the wrong direction, but as long as theres fans to keep and money to make, it's quite pointless to stop the Pokemon series here. No creation of a fifth generation would mean anime would end, TCG production would greatly drop, games of the "hero" type will end, and the fandom population will take a deep plunge. Honestly, it's just losing money if there is a new generation. Now, I am aware of the quantity of Pokemon being introduced, and how the number is quite massive. But animals and the number of species still have a far greater number than the species of Pokemon. I'm not saying the number of Pokemon should get to that number of the species of animals, but it should keep going on and on until the number of sales have found a plunge in the Pokemon gaming market. For me, Pokemon games are still as interesting as it used to be.
