The German still insists that he has another year remaining on his contract and has also been given the backing of team boss Norbert Haug.
"His race pace has been great, if not his qualifying, and we are all working very hard together for now and next year," said Haug. "He is totally committed and so are we - and you can see it in his eyes and in his racing."
After 278 races since arriving at Spa-Francorchamps for the Belgian Grand Prix of August 25, 1991, Schumacher is still looking for his first podium finish since his premature retirement in 2006.
His last win, of a record 91, was with Ferrari at the Chinese Grand Prix, but he claims his enthusiasm to secure another remains just as strong as he prepares to head back to Belgium for this year's race on August 28.
"Despite some funny rumours and stupid untruthful stories, I keep repeating myself that you will have to see me in 2012, whether you like it or don't like it," he told the Mercedes website.
"I will be there. And the good thing is that I have a lot of support from all around, in particular from the company, in particular from the team, that they all wish me to be there, so I wish to be there, and I look forward to it."
