I think it's potentially a big deal in broadening and deepening our knowledge, but I'm less convinced that it's about to upend history as we know it. My impression (and correct me if I'm wrong, I may be overlooking something) is that where evidence has been found for more intensive development than previously identified, it's been among cultures that were already known to have a fairly developed organisational capability, indeed that's often what drew the researchers to the site: the revelations seem to me to be quantitative advances (and important in their own right) rather than an overturning of existing perspectives. Angkor springs to my mind, its urban core found to have been bigger than previously thought and more intricately connected with the surrounding zone of intensive cultivation, but still not the the vast megacity imagined by some: the new information requires us to imagine a more ambitious scale and a more sophisticated regional supply network, but doesn't consign previous perspectives to the scrap-heap.

I actually do think there are towns (or perhaps we should say strongly clustered differentiated settlements) out there waiting to be found in unexpected places (indeed even where they're abundant the distribution suggests we're missing lots), but the ones I have in mind are modest local centres and trading posts strongly integrated with the adjacent territory or with more distant similar locations, which I find more interesting than the higher-profile tribute cities or ceremonial complexes that will doubtless also turn up, because it's the less ostentatious sites that rely on exchange rather than status, hinting at an active economic role and greater regional complexity.

Either way, it's an exciting technology. I'm happy with whatever turns up, even if it's nothing: a negative finding is itself a positive addition to our knowledge (and in fact I wish they were more fully reported: knowing a location's devoid of any unusual feature that might have been there tells us something of value even if it doesn't make the headlines). Let's see what turns up, it's all good stuff. But I'm not expecting any wholesale undoing of our current broad picture: just more to go on will be fine.
