It is expected the PDVSA-backed Spanish grand prix winner and Venezuelan will secure a new deal, but the famous British team is yet to announce its decision.
It is believed the only real uncertainty is over Maldonado's next teammate, amid speculation Williams intends to replace Bruno Senna with the Finnish rookie Valtteri Bottas.
Maldonado told EFE news agency: "I'm sure next season will be better for the team, better for me.
"So far no one is confirmed (for 2013), neither Bruno nor myself, but Bruno has done a good job this year and contributed to the development of the car.
"Let's see what happens in the coming days. I hope to have a quick response and be confirmed," he added.
Maldonado, 27, said he enjoys being the driving "spearhead" at Williams.
"I really like the team and I think for a guy like me there is no better place to be," he said. "I would still be the spearhead of the team, the first driver."
