Great to see we're finally getting an SSD by default in consoles. The only thing I'm worried about with this is the fact that high capacity SSDs are more expensive and with a push towards more digital storefronts, I'm wondering how this will work for the users. Then again, it's also a wonderful chance to push streaming, so there is that too.
I think consoles are a perfect fit for a fusion drive like in some Apple models. I have tons of games on my Xbox that I'm not going to play any time soon, but don't want to delete. They can be swapped to the hard disk, while games I play more often get loaded onto a smaller SSD.
So at that point of needing a pretty big SSD, make the console less expensive by only having the SSD, then let the user plug in a cheap external hard drive. Five minutes to transfer a game is pretty reasonable.
