The Xbox 360 (2005–2016) was succeeded by two console generations:
| Gen | Console | Year | Key Spec |
|---|---|---|---|
| 7th | Xbox 360 | 2005 | PowerPC Tri-core, 512 MB, DVD |
| 8th | Xbox One / S / X | 2013/16/17 | x86 Jaguar, 8/12 GB, Blu-ray |
| 9th | Series X / S | 2020 | Zen 2 / RDNA 2, 16/10 GB, NVMe SSD |
The "after 360" answer is already history: Xbox One → Series X|S → whatever's next.
