I think they'd have to be careful with how 'game-y' control bits are integrated with the design.
Assuming this approach of 'neutral' devices that have the next generation of portable Playstation rolled into them, I do not know if sticking conspicuously game-y bits onto it is a good idea or not. Of course at the same time we're presuming they want to support 'serious' games. So balancing that would be one of the other big challenges.
It is interesting to recap recent history though, and you can perhaps see a picture forming depending on how much you read between the lines.
First Sony partnering on GoogleTV. This isn't just about GoogleTV in fact - the companies actually announced a broader alliance centered around Android, something that was easy to overlook. Google TV is apparently only 'the first step'.
Press Release:
Sony and Google Establish Strategic Alliance to Deliver Compelling New Cloud-based Products and Services With the Android Platform
Sony Corporation (NYSE:SNE) and Google Inc. (NASDAQ:GOOG) today announced an alliance to provide a range of new and rich entertainment experiences that combine Google's open-source Android OS platform with Sony's expertise in technology and product design. The two companies are exploring the joint development of compelling new Android-based hardware products for the home, mobile and personal product categories.
Going forward, Sony and Google aim to maximize their respective industry-leading technological expertise to deliver products and services that empower users with easy access to compelling content, whenever and wherever they require it. The two companies are also exploring extending the alliance in connection with Sony's wide range of entertainment assets to establish new forms of cloud-based user experiences.
In interviews, Stringer is BIG on this deal. It seems logical Google would very much desire Android in on Playstation hardware assets. It is perhaps noteworthy that the people in charge of GoogleTV are a mix of former Vaio and SCE people who are working under NPS - Kaz Hirai's division.
One other interesting thing is that at the time this was announced, Stringer was also pressed on how he saw Android and PSN/Qriocity co-existing on Sony's TVs, with the obvious suggestion that there might be conflict; but he was pretty dismissive of that, saying that they were two channels that would be unified on Sony's TVs. That's perhaps an easier trick on TVs where the content is movies and video, not software...but still, I thought it was interesting.
The second notable stuff is these WSJ rumours, and also more directly a WSJ interview with Sony's CFO, Nobuyuki Oneda, who said Sony 'has to develop a device similar to Apple's iPad tablet computer, because it is a different product category than the company's existing electronic-book reader.'
Then, in June, SCE trademarked 'PlayView'. It carries a litany of classifications that seem very relevant (including "Portable electronic device for receiving and reading text and images and sound through wireless Internet access", "Downloadable video game software", "Tablet computer for e-book reader", "Downloadable music files" etc. etc. etc.)
So, without wanting to put 2 and 2 together and getting 5, there might be something brewing under SCE's direction. If Sony/SCE was making tablet-like devices (or more), after that Google alliance, it would seem very strange if it wasn't powered by Android, or a flavour thereof. Question is how/if Playstation fits in. If the next-gen portable Playstation platform is being rolled wholesale into the above scenario, it would be a very big mark on the road for Playstation in general. The ramifications would be potentially huge.
Sorry for the thinking-out-loud, but I was wondering if we were speculating too far ahead with the whole Android connection, so I went looking for more info, and thought others might benefit from the re-cap too. But it actually doesn't seem so far-fetched looking at all that's been going on the last few months.
