Main weakness of Sony, MS and Nintendo..in your opinion.

Okay, I've not read anything past the opening post, so if I repeat something, it's not a copy... :P

Nintendo: The inability to get 3rd party support. Nintendo's games are almost too good on average, and this scares away others. Coupling this with what some of the old developers started thinking during the SNES days, and it seems like Nintendo will never be able to get rid of this old feeling. Nintendo switched away from cartridges, and had a decently powered system (GC) and a relatively weak system that's cheaper to develop for (Wii), and the 3rd party companies always bitch about how the system can't do what they want. I truthfully think some 3rd party companies will never take Nintendo seriously again.

Sony: Profitability. Selling your system at a loss works if you're so far ahead that you sell the games. But if you can't assure yourself this position, as the PS3 did not, then you just don't make money. Businesses aren't charities- they need to see a return on their investment. When said return is negative, the business can't be around forever. To date in the US, the base PS3 has yet to be sold for profit. I'd also cite insistance on new formats as a weakness (no 2 systems have had the same format yet), though I'd like to hope this will change for the PS4, and it will keep Blu-Ray.

Microsoft: Reliability. The newer Jaspers may be better, but the stigma will not go away, even upon releasing the 720. The original XBox had issues, and the 360 has issues, so there will be some people mistrusting the 720, even if it's more reliable than Nintendo's systems. And I can't blame them- when a company is 0 for 2 in creating a reliable system in the consumer's eye, they're going to be leary of #3. Maybe third time's the charm? If they screw up the 720, though, I think they're done.

And for shits and giggles, a few other companies:

Rockstar: GTA, GTA, GTA!! What, we have to make a different game? Okay... *game flops* GTA time again! When the GTA cow dies, they're going to be in a world of hurt.

Square-Enix: Sure, we'll try new games. But we have to call it Final Fantasy something. I fear that they're watering this brand down, to the point where the name will get enough confusion and not be trusted by some anymore.

Sega: They seem to forget that they don't have the dominance they once had. They're still making the games that they think would help sell their systems, despite said system not being around and their fanbase fractured.

...I may post more later if I think of it...
