If you pay $12 for next months bundle, you will get a key for ARK: Survival Evolved immedietly. If you are already a member and choose to wait it out for the pay-date (1 week before March bundle launch), you will get a key for the game then.
The other games are unknown at this point.

Bit disappointing that this month's bundle only had the 1 really popular game in it. On the upside, it also includes a few games DRM free (not steam keys) and some games were both steam and DRM-free. Big thumbs up for that at least. Given how disappointing this month was, I expect next month to have a few other really decent games too.
To me the appeal of those bundles are that they may have a few hidden gems I've never heard of before. Having said that I have never pulled the trigger on a monthly sub but that's more to do with the number unplayed games in my library though I still manage to buy a bundle at least once a month.
Thats a lot cheaper then the current Steam sale price and SteamDB's lowest recorded price in USD
