My views,
PS might introduce 1000cc varient of suzuki swift, by replacing cultus, as on a current swift assembly line they only need to change the engine.
OR
They carry on with the same 1300cc with some little modification in specs like rimz, powerwindows and it might be lesser then the current swift in price.
OR
In 1000cc variant thay introduce suzuki Alto by replacing the cultus (Which i suppose not).
Lets see whats in their minds. Above are my views.
