I think the 8th gen consoles may get AAA support longer than we're used to for two primary reasons:
1) lots of people are going to have trouble getting the new generation systems for at least another year, it seems. So, there will still be a lot of active gamers on the last generation consoles for a while.
2) It just isn't hard to make the games work across all of the systems, since they're all basically just PCs now. Porting costs are low, in other words.
