I vote for option #3: collect more data before making a decision.
This situation is not a good candidate for a poll-based decision making; a mob of users having no experience with FB pages, advertising, etc. lack the basis for making an intelligent determination on the subject. Enacting a decision determined by any such arbitrary community vote is action taken for the sake of taking action, not because it's necessarily beneficial in any way.
Sit tight for now. Use both pages, experiment with promoting them, familiarize yourself with the implications of managing the two separate pages and in due time the optimal course of action should become obvious. Since the pages can be merged at any time, there's no need to rush into anything.
Also, having two separate pages for now gives a good opportunity for split testing. For one thing, what methods did tk use to amass so many likes? Most of the likes on the War2combat page are (I think) from Burton's FBA campaigns. He's run quite a few now but still only has 1/4 what tk's page has. Did tk run more ads? Were there other methods of promotion? Is it just that the page is older? Or is it in some way more "likeable" than war2combat? Maybe "War2 Tides of Darkness" is more immediately recognizeable for what it is, whereas "War2combat" is ambiguous.
Another thing -- if you merged the pages and people start seeing posts from War2combat on their timeline, they might not even connect that with the War2 Tides of Darkness page that they originally liked. etc etc. There are plenty of factors like this that need to be considered before doing anything.
