This is such a strange and incredibly specific idea you have. It's not as though SEGA would ever ever do exactly this, let alone anything even remotely like this. You are asking for a very specific laptop with TV out capability, hardware specific controllers, official emulation of dead platforms, and you seem to be describing SEGA's own proprietary online marketplace.
I'm just confused. You say SEGA should release a Wii-like console, then you say they will never release an underpowered product. But then you say they will not be competing with Sony and Microsoft. At this point, do they even have competition in this dream console you're describing? And if they don't then that means there is no market for such a thing. No competition = no market.
SEGA has been playing with the idea for several years. In addition to the 2011 "Kids Pad" prototype, SEGA also licensed out its console skins to Japanese PC retailer Enterbrain in 2013.
A Wii-like console does not have to be underpowered. Sega doesn't have a history of releasing underpowered products, maybe Mega CD in Japan in 1991 and 32X in America in '94, but then again, those were just attachments.
Being an Arcade giant, SEGA DOES have architectural talent for Hardware. The cool thing about SEGA consoles was their unique, schematics and ergonomics. Mark III/Master System trounced Famicom in every way. Mega Drive may have been 2 years behind Super Famicom, but it has both better sprite resolution and a faster,much more balanced Microprocessor.
Saturn was superior to PS1. It was just misunderstood and never fully realized.It wasn't a nightmare to program nor was it as convoluted as people claim. It was Sega's failure to channel enough resources to teach people properly how to utilize its hardware since Sega of America wasted all of 1994 on 32X and Sega of Japan failed to properly communicate with them.
Dreamcast was a superior.better design console than PS2. WAY easier to program, WAY better at anti alaising,cheaper,much more refined,better optimized. SEGA just didn't have to money to compete since they blew most of it on the FAILED GameWorks chain.
I don't understand why people think SEGA is going to have to immediately compete against Sony and MS. Sony is not the same big conglomerate they were in the 90s. They have FAR less capital(They're market cap back in 1998 was over $70 billion), and far more divisions that are nearing red. Why do people think that just because they have ONE successful product the PS4 that's only making semi decent profit for the whole company that SEGA who clearly has much more cash flow couldn't compete?
As of 2015 Sony's cap is only $32 billion. This is a far cry from 1998.
I see. They still think that its 1998. That Sony can crush their competitors with deep pockets. They don't realize thats something Sony no longer has. Sony lost a load of market value,capital, and money the past decade. PS3 and its 7 year development cost them over $10 billion in budget losses and the company's large divisions started to sink in red.
Also your forgetting something. once SEGA Holdings,Ltd opens for public trading, they'll very likely sell off SegaSammy's capital to Toshiba.
