I would hazard a guess that next years GP series will contain 13 out of the current permanent 15 with Artem and Antonio replacing Zorro and Tai...all barring serious injury or retirements.
I can't see BSI/IMG ommitting both Brits, doesnt make commercial sense to them, so Bomber will have to be handed a pick, which then makes it very difficult to justify ommitting anyone who finishes above him.
Only way I can see Janusz getting a permanent GP spot is if either Greg or Nicki call it a day.
One other rider that could be in trouble if he falls outside the top 8 would be Hans, but as said above how do you justify to Hans he is out of the series if the hand Bomber a wildcard.
