If you look at the PS vita + vita TV combo it's kind of like the original switch. Maybe next generation Sony will do something more serious in the portable market.
I'm not so fond on the subscription idea though, unless it's linked with PS Plus. I don't want to pay for more subscriptions, or pay more money. Plus once Sony gets a sniff on confidence, their services drop in quality. The last two/ three years of ps plus have sucked in comparison to the PS3 days, only in the last couple of months has the quality picked up again.
