So... you're basically saying Sony and Microsoft already made their money because those products are already shipped. However, for them to make anymore profits, those products need to get off the shelves at a fast enough pace to warrant more shipments.
You have been positing that a $99 pricetag will cause a significant boost in hardware and software. However, if it was so obvious as you were making it out, then this would have already happened. It may be already too late because we are over 2 years into this gen. For the PS3, some of its best games have been/are being remastered for the PS4 such as the Uncharted series, The Last of Us, God of War III, and Valkyria Chronicles. For the XB1, it has backwards compatibility for certain 360 games.
And in response to your response to my previous comment, I have not ignored games, accessories, and such. In fact, you basically ignored my previous comments and jumped the gun. I mentioned the XB1's BC earlier, which you have clearly forgotten, for instance. The PS Move is compatible with PSVR. It has found another purpose other than being a Wiimote clone. Kinect 1.0 has been extremely quiet and I doubt it is doing any significant numbers. You claim that the PS3 and 360 are close to the Wii U worldwide, but do you have citations for that claim? Media Create numbers show that the PS3 and Wii U aren't close at all.
Overall, your claims are based on your feelings, rather than empirical evidence. You need to show proper citations, show trends that show that PS3 and 360 are still viable and a price drop can yield bigger profits. You haven't done any of that the entire time.
Uh no your claims are based on feeling and you still haven't refuted anything.
Heck your using a bc argument that has a proven history of having marginal to zero impact.
You don't have an argument saying old 7 year old games are being remastered for the ps4 when that's not the argument. There are 1-3 year olds that have been charting and selling well. Heck, nee games from the last year til now have been selling. W have actual charts to show this fact so uh what?
