And perhaps, if we all beg and plead, it will have a modular map!
I'd be very surprised if it did. They development and testing effort for modular systems is far higher than for fixed systems. I doubt that either Mayfair or Martin would want to invest that level of expense in a niche game.
Then I won't have to sell a kidney for 20,000 leagues under the sea. Are there any other modular expansions out there?
Asides from the question of how well that particular map ruleset works as a design (I think it has problems), there's also Lajos' DIY system which can be used for making modular maps as well as Richard Irving's system for home grown maps.
