Marketing will be in the foremost thinking of Tesoro when the put a new detector out on the market. There isn't really to many ways for them to go as I see it.
They can either find a hole in their existing product line and squeeze a model in that, or
They can expand their line into something more than what their standard models do, or
They could drop a model that's a non mover and slip something back into that slot.
One thing I don't see ANY company doing is to put a new model out that would kill the sales of all of the other current models, that's just not going to happen! Moving on from Tesoro because a person can't wait for some All New And powerful Breed Of Machine doesn't make any sense to me.
