According to Toyokeizai Online, Sony's President, Kazuo Hirai, has gone on record stating that there is a (slight) possibility that the Playstation OS will find its way onto a smartphone in the future.
As it stands now, Apple's iOS and Google's Android platforms reign supreme in the world of handhelds. Should the gaming-focused Sony decide to toss its hat in the ring, we could see some big advancements in smartphone gaming in the near future. Add to this the similarly games-focused Microsoft and their smartphone version of Windows, and we could see four major players in the battle for smartphone OS supremacy.
Here's a piece from the interview with Mr. Hirai:
Interviewer: Do you think it is necessary to make all Playstation games playable on the Playstation OS?
Hirai: The Playstation OS is a very important asset for Sony. There's no telling what kind of interesting developments can come from the Playstation OS.
We are doing things differently now, and, along with Sony Computer Entertainment, we're looking into what is possible. As of now, we're only working with Android, because that's what the market dictates.
If the market changes, we might start looking into other OSes.

Even though he's simply answering the interviewer's question, it's clear that Mr. Hirai understands the Playstation OS could be something of a trump card for Sony, but the question is when he will decide to play it.
In the first half the interview, Mr. Hirai also had this to say:
[To prevent Sony products from eating into sales of other Sony products,] we'd like to make it so players can enjoy Playstation games on the Android OS.
The usually pragmatic Mr. Hirai looks like he's first interested in bringing Playstation games (ports, original content, etc.) to the Android OS. Then, as another option, possibly...maybe?... getting a standalone Playstation OS?
The joint venture with Ericsson ended last year, and now Sony has a bit more leeway in what it can do. It sure looks like there may be some big changes at Sony under Hirai's leadership.
