Launching the iPad Mini without 3G or 4G connectivity would keep costs down, which could allow Apple to price the tablet in line with its 7-inch rivals.
According to the sources the new products is likely to be launched in November.
One company, Knomo, which designs cases for Apple products, said on Tuesday that it would have an iPad mini case available within days, even though no invitations have yet been sent out for any launch, the report said.
