I am getting one because I already made the decision months ago to budget for it and will also trade in my current PS5. I imagine a lot of enthusiasts have done the same. It's not like rumors haven't been preparing people for Pro for a while.
In terms of the price, it is disappointing. Higher than I expected for a device without a disc drive. I'd have rather had 1TB less space in exchange for the drive as I already have an extra 2TB M.2 drive in my PS5. Not a deal breaker though if the console can deliver on its promises. The presentation was a little lacking so that's hard to say.
I wouldn't make any grand declarative statements based on this thing. It's a luxury item for people who really want it and see a value in it. The base PS5 still exists for most people. Disc drives still exist for people like me with a physical collection. Don't pretend this is a PS3 $599 moment because now you have options.
I'd be more upset that the base PS5's price is increasing and not decreasing over time, and is also trending towards a disc drive being optional. That's the mainstream device we're talking about here, not something like the Pro which maybe 10% of the audience will opt for.
I'd also be more worried about what PS5 Pro's price means for the PS6 in ~2028. The PS4 Pro launched at $400 in 2016. The price of the base PS5 has outpaced that because of inflation. The base PS4 had also been cut to $300 by the time its Pro model launched. I wouldn't be surprised to see PS6 launch for at least $700 - and we'll probably just shrug it off like a $550 PS5 now that the economy has gone to shit.
