Klitschko, who holds the WBO, IBF and IBO belts, said he was defending against Chisora on April 30 and expected to battle WBA champion Haye on July 2.
"It's going to be a very exciting year," Klitschko said at a Grand Central Station promotion for a new boxing TV series.
Klitschko and his older brother Vitali, who owns the WBC heavyweight crown, offered Haye his pick of the Ukrainian brothers in their aim to amass all the major boxing belts between them.
"David Haye said he doesn't want to fight Vitali because Vitali is hitting too hard. He said he wants to take the little brother," Klitschko said in the train station's stately Vanderbilt Hall standing outside a makeshift boxing ring.
"It's the truth. The fight is going to happen. We found a date, July 2," said Klitschko, adding that the formal deal was yet to be signed.
Klitschko said a site was to be decided, though it would be staged in Europe.
He was to have fought Chisora last month, but called off the fight because of a stomach muscle injury he suffered during training.
"I want to stay active because I fought in September, so I'm definitely going to fight on April 30 against Dereck Chisora, another British guy that I was supposed to fight in December."
