Maybe the N54 will be used as a higher output model in many BMW's producing around 350hp and the upcoming N55 could be the secondary engine producing 300hp.
And before rejecting this thought, think about how easily N54 can produce 350hp with some minor mods

I dont think the N54 will demise that quickly as it is still a new technology. I think they can only improve it instead of canceling it out.
