I'd really recommend making time for it, even over Diablo 3 (though I suppose you guys might be reviewing that soon). I never played the previous Tribes games, but Ascend really is a different brand of FPS, so I can only assume how fun the previous iterations were.
New Kickstarter by the guy who created Wasteland, Fallout, Interplay, etc. for a Wasteland 2 game. Turn Based, tactical, party based RPG, after hearing for your like of the original Syndicate, I figured this would be right up your alley.
