AMD CEO Lisa Su signaled that the company is ready to support the launch of a new device within that timeframe. However, it is important to understand the difference between a supplier's readiness and Microsoft's plans, since ready chips are only half the battle.
Supporting the premiere means only that the technological partner will do its part and deliver components on time. This does not guarantee that Xbox will go on sale in 2027. Microsoft needs to take into account the portfolio of launch games, current Series X sales, and rising component prices, especially for RAM memory.
If the rumors about a hybrid Windows console are true, Microsoft will have to solve serious software optimization challenges. Many believe that releasing the device in 2027 would be too bold, and that 2028 remains a more realistic timeframe, given that the PS6 will not appear before 2029.
