We're very close, as a matter of fact - just wringing the last few problems out of it. This might be a good time to remind everyone that our "request" list has grown rather small, but it still exists. We still could really use a few more units and graphics to make this mod 'complete':
I haven't discussed this with Tom2050, who's been busy in RL, I understand, but he was planning to make:
A Barsoomian Great White Ape
A Thark worker
Barsoomians and Tharks riding Thoats
...so I'll say status: unsure. I have a work-around, but I'd rather be able to include the units. I'm sure that unless he has it on his desktop, he won't mind someone else jumping in to finish one of these Barsoom Units. The White Ape is the most needed, followed by the Thoat Riders.
We also need two leaderheads:
A Pterodactyl Leaderhead
A Cthulhu Leaderhead
..either of which might be a good way to let your inner artist have a go at it, perhaps.
And that would be it. Done. That part of it, anyway.
The main mod elements - the graphics and Civilopedia - are almost complete. I keep finding previously-hidden problems - it's like fixing a clock with your eyes closed, sometimes. But, like the ape who keeps typing, I've accidentally got it right, for the most part. Anyway, when I've got that all done, the files will go to King Arthur and Blue Monkey for more testing and balancing, then, I guess, it will be released in beta form for more general playtesting. I expect most of that to happen this month.
This mod has been a long time in development - years, actually - and all of the 'carefully thought out..elements' (and all of the other nice things you said, 7ronin) are the reason that it's taken so long to put together. Some of our custom unit makers haven't seen their units in action yet, and we are well aware of that, but wouldn't want to waste their exceptional efforts on a less-than worthy mod. So please bear with us just a wee bit longer, and we will attempt to reward you handsomely for the wait.
