There are two major categories of concerned gamers in threads that relate to the Pro version of the PS4:
1- People who have the vanilla console and think that they are somehow screwed by the introduction of the newer system.
2- People who have had no intention of buying a PS4 to begin with, let alone another iteration of the plateform.
I used to belong to the first group. I was fearful of what a mid-gen upgrade would entail, but the information that has been shared since the rumors started circulating has put my mind at ease. I see no reason to jump, personnally, but I can appreciate that new comers and technology enthusiasts might be interested in doing so. Their decision has no bearing on the one that I made less than two years ago, when my PS4 was acquired, and I will be enjoying every game on my machine until the next one drops (PS5). There is nothing more juvenile that being bitter than somebody else has the money and desire to shell out $399 and enjoy the better version of software. How does it undermine my own experience, really? The only problem would emerge if developers were to start butchering the PS4 classic titles, relegating them to an afterthought...But that will never happened. There is something like 44 million PS4 users out there, and there is no way Sony will leave them in the dirt...
