I'm sure it's a good list of things
Seems like you are conveniently PS3's FULL backwards compatibility with the PS1 and PS2 at the very start of the gen.
Also, the PS4 controller works on the PS5.
Not all models could play PS2 games which was odd and it's not like they carried that forward into the PS4. It was an opportunity lost to build up on what they had with the PS3 but with MS shooting themselves multiple time in the foot with the announcement of the Xbox One it was one they didn't need. Instead they gave their customers an opportunity to pay for them again through PSNow.
They did a 180 on controller support? MS must be doing well since that wasn't the case before and people were defending that "it was because of the new controller features".
I stated "at the very start of the gen". The PS3 did phase out legacy support, and nothing points to MS not being able to do the same. Time will tell. So, ALL MODELS at launch could play PS2 and PS3 games.
As for the console, no, they didn't do a 180. The PS4 controller always worked on the PS5. The only thing it can't do is play PS5 games, as they will be tailored to the new features of the Dual Sense that cannot be replicated in said DS4 and have gameplay repercussions.
Since they include a DSense on the Box, this is not a problem. Also, I see it as much better to have new system features and new game features instead of legacy hardware support. You may see it differently, but sales will likely disagree with you.
I think in the EU it was different which is probably why it didn't even come to mind when speaking about BC.
That's just PR talk, there's absolutely no reason a controller gimmick would stop you from playing a game. Imagine not being able to play GT7 because your controller triggers don't rumble. The sad things is third party games may not even use it and you still won't be able to use the old controller...
Sure, additional controllers will be sold exactly because Sony doesn't allow the old one to be used. You also may see it differently but the vast majority of of PS gamers would prefer if they had full support. Since this post is about the console being pro consumer or not that's still a negative point I'm afraid.
Not rumble, pressure. If your mechanic requires pressure sensitivity and the force mechanic, it wont work. Something tells me you know this but want to be disingenuous.
