Next year's event will be the third and last under the current contract.
But talks will take place between World Cup partners, including Manchester City Council, to extend the deal.
The 2006 competition closed on Sunday night with a world record-breaking weekend in the pool and on the track.
And it prompted Phil Lane, chief executive of the British Paralympic Association, to tell M.E.N. Sport: "We have moved up a ladder from last year. We learned lessons that enabled us to engage more people in Manchester into what we are trying to do with the World Cup.
"It was tremendous to see all the school kids watching the wheelchair basketball last week and even though the weather wasn't brilliant yesterday, we still had a cracking crowd.
"The day we stand still in this event is the day we start to go backwards. And what we won't do is compromise the quality of the event.
Committed
"There is one year left in Manchester but we're working with all the major partners to look at ways of taking the World Cup forward.
"VISA are very committed sponsors and it's fantastic we've got support from BBC Television.
"It helps us attract more people to watch Paralympic sport. So, by the time the 2012 London Games come round, they will be knowledgeable about what's taking place rather than just turning up to an event simply because it's there."
Mike Brace, chairman of the British Paralympic Association, added: "This event has improved from last year's event with greater performances and crowd support which makes me believe the World Cup will achieve further success in 2007."
South African sprinter Oscar Pistorius added: "Every athlete who I have spoken to has been full of praise for the Paralympic World Cup.
"It is wonderful to face annual world-class competition which can only raise the standard of our sport."
And Alan Pascoe, vice-chairman of London 2012, enthused: "Long term, Manchester can become the home of paralympic sport." Tweet
