Yes, but not for Android Updates, that is for sure!
Now, as an Fairphone owner, but also being hungry for power and Android Updates, the FP 3 definitely needs a new processor. There is no guarantee, but it should be state of the art at release time. Throw in three or four GB ram, a better camera module and LTE on both slots — done. The more I think about it, it’s like the S models at Apple. The new slim case, the display… all great with the FP2 already, keep them ans the battery for compability . If they can keep some more modules compatible, the better.
