For the iPhone 18 Pro (Marley), which has a standard design and size, the situation looks good because initial indications suggest that the waiting period, i.e. the period from the date of order to the expected delivery date, is lengthening; This is what people are always looking for to say: " Well, it seems that demand is increasing because getting this device will take longer."
Pre-orders only started on September 12, so there isn't enough data, but the first week is what people are focusing on. The iPhone 18 Pro looks promising for Apple.
