Why it matters

Platform, chip and AI decisions set the terms other companies have to build on, so a single announcement here tends to ripple through products, supply chains and regulation.

What to watch next

  • Availability, pricing and rollout regions
  • Independent testing or verification of the claims made
  • Responses from regulators and competing platforms
