You are entitled to your opinion, I am going on what I am reading and being told by people in the industry.
The overall opinion is that gaming has crested and is fading. now I am not saying it's all going away, there will always be some gamers. However, fewer people will be needed to service what is still going to be around. As you said if Apps are the only thing growing, you don't need people to design games systems and you don't need people to design games for individual systems. A game is designed for all the apps.
The bottom line is you need much fewer designers.

I hear you, but we'll have to agree to disagree. I have hundreds of friends and former coworkers who are still in the industry, and thriving.
Just to give you an impartial reference, here's a recent Gartner press release regarding a white paper on gaming industry sales growth. It's not dying. It's growing every year. The only changes are that the pie slices (types of games being sold) grow and shrink and redistribute as different technologies (PC, console, phones, tablets, etc.) come into play (no pun intended). Human beings will NEVER stop playing games.
