hmm well last week the big patch had a massive delay.. so they said they'll have an exp boost as soon as the server was back up... + the weekend...
Edit: Found the announcement from last week

but.. it felt the boost is still there? O_O
now i'm not sure if its normal for me to get 900 exp from a red stonie in duo party... i thought i usually get about 700
