I too believe Sony can once again be a dominant player in the hand-held gaming tablet. To that end, if Sony can leverage its experience in PS-x series and implement in the hybrid tablet-gaming device integration, it can take a commanding seat.
Further more, if integration of such functions can also enable RF4CE and second-screen (or overlay screens) in live broadcast, I think Sony will be a dominant player in handheld and big screen TV market.
Back in the 80's the founder dude wrote a book, and claimed that American workers are lazy blah blah blah. Looks like KARMA has begun. Sony invented nothing, they copy. Like what Samsung and LG are doing now to clobber Sony and Panasonic. Panasonic at least does a lot more stuff beside CE toys. Sony is toast, Panasonic will survive, Sony will not. They are selling off, a movie entertainment business they BOUGHT years ago, they didn't create it. They are nothing. but a marketing company, which is failed. PHILIPS broguth them the CD and cassette, whihc they marketed portable cassette player and implied they created it! PHILIPS brought them CD, a working CD system, cus Panasonic didn't want in, which was DUMB.
I don't expect them to be able to make inroads in laptops and tablets if they cannot compete in phones (which they are not doing in the US). People seem to want the biggest screens or the highest resolution. If you don't have that it's tough. A 4K, 3D TV technology would be interesting if it could catch on but a media method would be necessary (blue ray is inadequate). The reason I bought a PS3 was to get a cost competitive blue ray player. I'd never buy a PS4 unless, for example, it enabled 3D, 4K technologies. They need to make it advantageous to buy a Sony phones, DSLR, PS4, TV, and receiver because if you buy all of these, then you get seamless transitions from one to the other. Samsung is on their way to accomplishing this. Otherwise, it's not really anything different that what everyone already has.. Almost every major DSLR maker uses Sony's imaging chips. Yet Sony has this technology in their pocket... They need to get nasty.
I see two factors explaining Sony's weakening electronics market. First, consumers are emphasizing portability (MP3 players / iPads to watch streaming TV programs online) over fidelity (CDs, expensive sound systems, ultra high definition TV). Secondly, there are serious concerns about which technologies will become mainstream in the long run. There are so many high definition and 3D TV options that consumers are waiting for the dust to settle to determine what to get; these technologies are not "impulse buys".
Lately, luck doesn't seem to be on Sony's side. The image quality of their TV is spectacular. The stunning reality of 4K and the progress of 3D TV with a $10 passive 3D glasses take my breath away. I couldn't really figure out why it doesn't sell. Maybe, they lose to Korean's brand because of price. Maybe, they didn't manage Chinese manufacturer well enough to maintain the production quality. Who knows and they can't care of the history too much now.
Their direction seems to be logical. Cloud based service and mobile computing are no doubt continuing to drive business in the next few years. Question is whether Sony will be successfully leveraging cloud-based service and their expertise in mobile device to drive the sales of the other platform (e.g. PS3/ PS4 and TV) and vice verse.
Technology is important. Marketing seems to be one of the key drivers. I don't know how many people know the integration Xperia Tablet Z and PS3. I learn it just a few weeks ago. I am pretty sure there will be amazing technology coming through the moving. Question is how popular it is going to be.
