I have a lot to say on this topic, but I'll cut out / abridge some stuff.
Pokemon EX are not going anywhere any time soon. The reason is that they are currently inextricably tied to mega evolution.
I think people underestimate the huge impact on the entire series of Pokemon that the introduction of Mega Evolution was; perhaps moreso due to this being a heavily-TCG website. It's not just a mechanic that will be here for Gen 6 and then magically go away without explanation. It's not just a generational gimmick. Mega Evolution is now just as tightly incorporated into the very DNA of the nature of Pokemon as regular evolution, or triple battles. If suddenly people "have not discovered M-E" or something in the next generation I will be very surprised.
Perhaps fortunately, the TCG is releasing Megas faster than Pokemon is creating them. There are 46 species currently capable of M-E; only ~15 still don't have Mega cards (some have regular cards but no M-EX; like Camerupt and Sharpedo). Eventually they will run out. Only then will the flow EXes have a chance at diminishing. As long as we have Megas, though, I have a feeling EX is here to stay. With every set they are becoming more and more solidified as a permanent addition to the TCG, I think. And they are toning down the power creep a little. PCL could pull the plug any time they wanted to, but for countless reasons I don't have time to go into (some of which are above anyways) I really don't think they'll be axed any time soon.
