1. Monster Hunter declined as have virtually all major 3rd party games including Dragon Quest and certainly Final Fantasy, and the vast majority of A/AA games. Nintendo's first party games on the other hand kept climbing, it's an utter monopoly. Rise barely or moderately outselling World in Japan isn't really a feat when you consider portability and the massive popularity/install base gap between PS4 and Switch. MHRise will not achieve the numbers of Portable 3rd, which came out on a system not nearly as popular as the Switch. The series definitely declined in Japan despite the insane growth in the rest of the world. But thankfully the decline isn't as severe as Final Fantasy or Resident Evil or Gran Turismo, etc. It does seem to have the potential to bounce back if released on Playstation and Switch simultaneously (Dragon Quest couldn't with XI).

2. Pretty sure the ratio significantly increased compared to PS4 at launch. PS5DE being digital only will accelerate the ratio growth even further, as will Series XS.

5. No it isn't the norm. PS3 and PS4 weren't backwards compatible. Anyone who bought the PS2/PS3 version of a certain game bought it to play it ONLY on the native console. This may not apply PS4/PS5 if my understanding of "Dumb Delivery" is correct. It looks like at least in some cases, PS4 version works on both (and most give you a free upgrade when a native PS5 version is available), whereas the PS5 version wouldn't work on PS4. In other words, PS4 versions are superior due to accessibility. In the case of Horizon 2 it's actually cheaper (PS4 version literally gives you more for less. It's ridiculous).

5. You are correct. PS5 physicals dont work on ps4. It just makes more sense to buy the PS4 physical version because it works on the PS5 too and 99% of the games so far are free upgrades. The only 2 games i know that cost $10 to upgrade are GoT and death stranding. Even with the $10 fee to upgrade, most people would still buy the PS4 version so they can play on both PS4 and PS5

Yeah, but the software for ps4 not increase but decrease go on, (the last white paper demonstrates this), the multiplat ps4/ps5 demonstrates this too. 

I don't know why the development story matters. If Dragon Quest maintained popularity, XI should have performed better than it did. I predicted around 6 million across the three version, because each one offered things the other lacked, encouraging double/triple-dipping. DQXI PS4/Switch and 3DS are essentially each other's remakes. Being accessible to a larger playerbase is the other factor to consider.

Don't worry you don't have to explain that lol. You'd be hard pressed to find anyone here who spoke against gauging success or popularity based on attach rates alone more than myself. But in the case of Rise vs World, the inevitable 300%-350% install base advantage of Switch over PS4 should be expected to translate to more than the increase we're seeing. I was expecting it to sell 4.5-5 million, which is a conservative figure compared to what many others thought here.

Going by attach rates, nothing beats World which launched to a ridiculous 33%~ attach rate at 6 million PS4's, and pretty much maintained it. I hoped that this was an indicator that the series may be growing in Japan (Peak popularity Monster Hunter sold an unimpressive 1 million on Wii), but Rise is under-performing all things considered. Rise launched to an (expected and fairly impressive) 10%~ attach rate, but it's not legging out particularly well with the install base in mind (slightly/moderately worse than I expected, but not exactly a shock).

The relationship between install base and software sales is certainly not proportional, but it's linear. The popularity of Switch just isn't being reflected on Monster Hunter Rise so far, and this indicates a slight decline in the IP's popularity in Japan.

It's actually kind of funny that Capcom refuses to release a Monster Hunter game on both Playstation and Switch. Would likely break Portable 3rd's record, but probably not when counting PS3's version.
