I actually said this on a post a month back. There needs to be four tiers of the PlayStation Phones.

The Gamer: It's essentially a Vita, but with extra shoulder buttons and analog clicks to properly support Remote Play. It would also feature AC wireless for more dependable connections, as well as optional 4G data.

The Phone: Think PSPgo, or Xperia Play. Two clickable analogs, Dpad, facebuttons, four small shoulder buttons, and touch screen/backtouch pad. This in the form of a slider phone, and is a phone first. Like the Gamer, it would feature AC wireless and 4G data.

The Tablet: No conventional button controls would be on this device, but would support a larger screen. Instead, it would ship with a Dualshock 4. Like the Gamer and the Phone, it would feature AC and 4G.

The PSTV/"Streamer": Not much would change about the PSTV, except the addition of AC Wireless. Would be packaged in with all PS4s, and the DS3 bundle would be replaced by a DS4 bundle. 

Changes across all "Vita" platforms:

1. AC Wireless

2. MicroSD Support 

3. Netflix, Hulu, Vudu, Amazon, Crunchyroll, PSnow, and Vue support

4. All platforms support Dualshock 4 connectivity. 

5. All platforms would run off of the PlayStation Store. The Store would feature an Apps section, a Games section, and a Video section. Apps would feature the same level of accessibility and diversity as iPhone apps. Games would be separated into "Mobile" and "Console", and movies would exist as is. 

The PS4's role: It would offer the highest end games,  but that would be it. It would continue to remain a device exclusively for gamers, where Vita would become a new contender in Touch OS. The PS4 would receive a new sku including AC wireless, but that would be the extent of changes for PS4 (don't fox what ain't broken).

I heard they were trying to move away from the Vita name. I don't understand that as "Vita TV" or some other brand sounds better than "PlayStation TV", and yes PS TV was a huge missed oppertunity in terms of sales. 

It plays Vita games on TV. PS Vita TV. It was overally simple and cost too much. Vita doesn't have much games already and PS TV have event less.

Sounds like we are pretty much on the same page. Only thing I would do different is continue to let PS4 grow. I don't see any harm in turing it into the defacto home computing device, as long as it is done in a manor that does not take the focus off gaming. 

The multi-skew approach to the mobile PlayStation branch is perfect, and atcually makes sense, unlike the current E, M, Z, or whatever they are called Xperia phones, that are essentially the same thing with a different name. With the stratagy you are taliing about, they can have a Typical Smartphone (See Xperia Z), a gaming phone (see Xperia Play), and a handheld (see PS Vita). That actually gives them devices that reach 3 very different markets and end users, but it puts everything under one coheasive ecosystem in PlayStation Network, and under one PlayStation OS. This gets rid of the relience on Google, which is great, (see Vaio as an example of where relying on other OS's ends up). 

Now all we need is some help from Kazuo Hirai, Kenichiro Yoshida, and Andrew House.
