During that March to July period you’re highlighting also just coincidentally happened to see the release of FF7 Remake, The Last of Us ptII and Ghost of Tsushima. The first peak in that chart is presumably the FF7 Remake release. 

Why ? It would had the same continuation, if not better, if it was in stock for the full 2020 and 2021.

You draw a line, and throw weekly numbers, but you forget that this compensated in the holidays of 2020, which were awful for PS4 and XBSX. If PS5 is in the same position and there's no covid, it will simply continue to sell those 140k weekly for the remaining of the year (maybe going down to 100k by october) and then have bigger boost than the PS4 in the holiday, which will end up at around the same level overall for the year. Well I am not talking purely about the numbers, cuz they can be different and probably will be, I am talking more of the ratio of the sales. Without covid, PS4 could continue to sell the same numbers weekly, and slightly decline over the months leading to the holidays, but then had a way stronger holiday. Just like PS3 was in 2013.

What arguments of mine does that contradict exactly?

COVID and limited production really hurt PS4 and PS5 hardware sales beyond the period you're highlighting. Seems to me that there is no reason to launch the PS6 sooner than 2028 or cut PS5's production too soon. "console wars" are transforming to "ecosystem wars". Sony won't care whether you buy a PS6 or stick with PS5 as long as you remain in their ecosystem and give them your money, and so I find it very possible that PS5 will continue to sell long after PS6 is launched, which could translate to a sluggish PS6 start (a large price gap, potential PS5 handheld, and a long crossgen period will do that).

I am totally clueless as to how Sony will handle the next generational transition, so the possibilities are too many. But were it up to me and assuming there would be no production issues/limits, I'd keep producing PS5's and sell them cheaper. No matter how powerful the PS6 is, its games will probably be easily down-scalable to the PS5 hardware for at least the first half of the generation. It would be a waste to end PS5 production as soon as PS6 is out. What point is in forcing people to upgrade when you're losing money on hardware? The wow factor is dead. Current highend AAA games are playable on SteamDeck ffs.

You said that its more than likley that the PS6 will have a DD wich i contradict because of said factors.

To be clear they only discontinued recordable blu-rays, nothing is happening to the normal stuff yet. Saying that you totally contradicted what I said is pretty silly when I literally said Sony will absolutely deprioritize physical if they keep it and that I think it's a possibility they might forgo it all together. There's really not much disagreement here so I don't get the justification for that.

For why I think it's more likely they'll keep it it's cause there will be a notable amount of backlash if they forgo it and it won't cost them much to offer it in a deprioritized way. Physical does still have a notable presence on Playstation so it'd kinda early but it'll very likely be gone for the PS7 since a decade from now physical should be tiny even on Playstation.

All games/ films that get BD releases get recorded on BDs. Before a film is on BD its an empty (recordable disc). If a wheel company discontinues their rims production, they will most likley stop producing wheels as well. The PS7 will be digital only 100%. I even would be my head on that! PS5 technically has no DD as well! You need to buy it seperatly, yet Sony only produce it in limited quantities. But hardcore fans (George Orwell 1984****) buy it no matter what. I guess even if Xbox had physical and PS skipped it, there would still be some deluded people trying to excuse it. One thing is for sure: They won't stick with discs forever and many things going on now like the discontinuation of BD even make a physical DD for PS6 debatable. 

My point is while they've stopped producing blank ones they're gonna continue being in the BD business for now, probably for about another decade or so.

I agree that's debatable though I kinda doubt it but lets just wait and see what happens since it won't be that long till we know.

The Switch 2 era will likely be all about 95 % of physical sales the coming 10 years being on Switch 2 games alone. Only Switch 2 games will show up on retail charts.

My point is that every game, film you buy on BD today was pressed on a "blank one". Film- and games BDs don't fall from the Sky. 

But you are right: Lets wait and see!😎

@Sephiran: 95% of all games in physical charts will be Switch 2 games next gen? Maybe not 95 as current gen (PS5, Xbox Series X) will probably still be around for a while but it wouldn't surprise me if your prediction came at least close to this number by the middle of next gen. By the beginning (2027) i don't quite see 95%, but i am in for a surprise.🙂
