Don't particularly disagree, but its pricing is comparable to other solutions on the market. If Scuf can charge $200+ for a controller, why can't Sony et al?
There are already existing 3rd party options. Sony are offering a different option with a different balance of advantages and disadvantages, particularly replacing thumbsticks for $40 instead of needing another $200 controller* when those are worn out. I don't understand why Sony should leave it to 3rd parties, or be expected to create a cheaper option. If I'm in the market for a high-end controller on PS5, I can choose Scuf or Hexgaming or Megamodz or Sony. If DS Edge didn't exist, I'd have one less choice and none offering replaceable thumbsticks.
DS Edge is too rich for my blood, I'd prefer better battery life, and I expect Sony would sell many more with better battery life and a lower price. As a gamer, I'd like an elite controller sold at cost - heck gimme a free pack-in game or two as well! As a business move, a product to make profits, this seems a reasonable option for the console company. It feels a step backwards in terms of consumer focus from PS4's days, with Sony's generally pricing feeling to be heading upwards - this is a completely different value proposition to the fabulous DS4 paddle add-on - but if I don't like it I can always shop elsewhere, from controllers to platforms.
* Though ironically possibly needing a new $200 controller instead of a $10 battery replacement!
