I think we both know the reason for that... and that's exactly the point of my argument.
I don't think the lack of support material for the exotic parts of FR is why most campaigns are set in the heartlands. I think it's because most gamers actually want a pseudo-medieval campaign setting, which is precisely what the Heartlands provide. The exotic parts are meant to be just that, exotic.
Numbers just taken out of my butt, but I don't think it's inconceivable that something like 75% of the FR fanbase are mostly interested in Heartlands campaigns, which would be spread over 9 or so regions (Silver Marches, the rest of the North, Western Heartlands, Dalelands, Cormyr, Sembia, Moonsea, the Vast, and the Dragon Coast - I may be forgetting one or two). Also, someone interested in the Heartlands would be likely to be interested in more than one bit of them, since there's a whole lot of interaction going on there.
The remaining 25% are the ones who'd rather buy exotic lands. However, these will by necessity have less detail (since you're using one book to cover like 3-5 countries), and people interested in one are less likely to get and use more (because the regions aren't as interconnected - there's a lot of travel/intrigue going on between the Dalelands and the Moonsea, but less between Aglarond and Amn).
So, any given Heartlands book might be interesting to 50% or so of the FR fanbase (2/3 of those interested in the Heartlands in the first place). Any given exotic book might rather be intereting to 5-10% (1/5-2/5 of those who'd rather have exotic books).
Of course, it's not that cut-and-dried. Of course, there are plenty of people who are interested both in the Heartlands and in exotic places. That's why I feel that it would be best to mix them up. Say, one Heartlands and one exotic sourcebook per year.
Oh well, that's one more advantage of Eberron. No arguing about whether to write new treatments of things done ages ago or to write treatments of peripheral things people rarely go to - because it's all new
