What if Cuba does not need Venezuelan oil anymore?

I just stumbled upon this piece of news on The Guardian. Apparently, the recent discovery,

"if confirmed, puts Cuba's reserves on par with those of the US and into the world's top 20. Drilling is expected to start next year by Cuba's state oil company Cubapetroleo, or Cupet."

If this were true, what are your bets?

- Hugo Chávez would feel less need to spend Venezuela's money supporting the Castro regime and he would be able to use it for good or bad in Venezuela.

- The Castro regime would get more leverage in Latin America

- United States would feel compelled to easy down the embargo.

Your bets?
