One of the two used to be the second biggest console manufacturer in the world, and is responsible for some of console gamings most iconic and enduring series.
The other is responsible for some of console gamings other most iconic and enduring franchises.
And? What does 1995 have to do with 2015? Nobody is going to dispute the history of these two companies. What's up for debate, and what I'm pointing out, is that neither of them have had much of a stake in console gaming for, what, 5-10 years? Their exit at this point is a formality. We've all known it was coming. Konami has been knee deep in slot machines and video poker for forever. Sega.. I don't know what Sega does anymore, save for really bad Sonic titles.
Don't play this off like Konami and Sega are some no-name companies that nobody should care about, wake up and smell the coffee that console gaming isn't a healthy market and hasn't been for quite some time.
For every chart that shows an unhealthy trend, there's a chart that shows a healthy one. (edit: you needn't look any further than the chart posted here. with handhelds, downward trend. without, upward trend) Economists and companies will skew it whatever way fits their narrative. Here's what we know as fact: Gen 8 consoles are selling like gangbusters right now. Sony recently announced that the PS4 has sold through over 20 million systems in 2 years. That's the fastest Sony has ever sold a console. The PS2 didn't even sell at that clip.
I'm not going to sit here and tell you that it's going to continue to sell at this pace, because it won't. But that kind of doesn't matter in the here and now. Right now, it's selling. It's selling a lot. And that is pretty much the exact opposite of an unhealthy market.
