hmmmm Christmas break should be really good for them, people will have more free time to play the beta and give their feedback. Furthermore (this is more personnal ^^) this would be a wonderful Christmas gift, just imagine on the 24th you receive a mail with Santa's pic saying "hé now you can explore Rivellon, merry Xmas... oh and beware of weresheeps" ^^

"-Oh that's fullmoon, cuttie cuttie sheep
-baaaaaaOOOOORGH"
***Sprotch***

Weresheeps will rule the world (At least one night every 29 days)
