After hints that a new Deck might be coming, it seems that the Steam Store page for a new Deck finally confirms the rumors:
- HDR OLED screen
- WiFi 6
- Bigger top model with a 1 TB SSD
- SOC on a smaller node
- Larger battery, which combined with the more efficient APU results in 30-50% more battery life
The initial drop will be in the form of a limited edition run".
