I don't think they will drop Helder because it's way too unreasonable at the moment. Countless reasons not do it.
Did Helder receive an offer he couldn't refuse from KTM?
I think there's more analogy to this in WRC with Loeb/Sordo/Ogier/Hirvonen shuffle in the past three years.
Someone may be benched for a few years, someone will take a step back and the king will be king.
