Apple to switch Mac lineup to its own chips

When Apple switched to Intel, and to OSX, we lost a lot of great software. But the computers and the OS were so much better it was almost worth it in a lot of cases. (The bigger loss was the change in general aesthetic and culture of independently developed Mac software. But that kind of change is also inevitable over time regardless.) Will we see that here? Will there eventually be compatibility tools? Will we be stuck settling for a lot of ported iOS Apps on Macs? Will it not matter because so much stuff will be browser/HTML based?
