casinos, and quite possibly resorts as well, are no longer novel.perhaps the issue is the question is faulty. what i mean is, the original flamingo was not the answer to a question, just like the desert inn wasn't, nor was the mirage or bellagio. the next great thing is just that because of originality and meeting a need/demand that is not presently being recognized/served because if it was, it wouldn't be a need or demand. those resorts worked because they did not answer a question, they were revolutionary. the next phase of mega resorts to me may be an oxymoron. that is if the upcoming ones fail because they don't work with the next generation like the resorts i mentioned above did with their respective generation. as a contemporary reference, 'city center' in hindsight would never have been built, at least not in it's current scale because it never really worked as envisioned. the cosmopolitan is successful because of its scale, location, and just as much for what it isn't as what it is. sorry if this reply seems sorta don draper-y. i just think this question may be sorta a 0 denominator type.
