I voted 10-11.9m. No way is PS5 selling better than PS4. I can't believe how many people actually think this will happen. Some things to consider:
1. $500 price tag
2. Looming recession
3. PS5 has much tougher competition than PS4 from both Nintendo and Microsoft.
4. Launch data is basically irrelevant. Even the Wii U sold well when it launched.
