I can confirm that statement in spades. 200s are ubiquitous in Saudi Arabia, Bahrain, and the UAE. I haven't spent enough time in Kuwait, Jordan, or Oman to have an opinion but they are poorer counties (except for Kuwait) so maybe not quite as many 200s.
Just to add, I see statements on this forum all the time suggesting that the 70 series is Toyota's "flagship" or largest seller or whatever. I see 100x more 200s, Prados, and maybe 200x more Hilux pickups than 70 series. Would be interesting to see "non mining" sales of 70 series vs. the 200. I'm guessing the ratio is very low. In fact, I probably saw more 70 series in one day at one of our mines than on the road in 6 months.
