Goven,
Apparently this extra money is because they bought some planes to stop drugbusters, so its us the tourists and wealthier Dominicans that fly from airport to airport for their breaks that they are getting the money from as its easier to collect on the people that fly in and out of the Dom. Rep(dont know how true this is).
Your right the Dom Rep Embassy has not updated their site but if you buy the Tourist Cards online they are printed with how much you have paid, so on arriving in the Dom. Rep once the fees have gone up they will make you rebuy them there and then, once home you will have to contact the Dom. Rep Embassy for a refund, we had to do that one year when they had changed from a paper form to the cards they now give out.I bought in advance and the Embassy did'nt tell me that they were changing before our holiday dates took place. So they will get you either way and then becomes a hassle at the airport.
Here is a link at what they look like at the moment and the Blue form underneath them is your Immigration form that will be given out on the aircraft to fill in and handed in at Passport Control, you will also get one from your tour rep for your return.
