I'd imagine this is more an indication of how well liked their current device is rather than Ps5. If PS4 tanked then 5 wouldn't get this much attention, but because it had amazing sales everyone was interested in what was coming next. I'd more so be interested in seeing what percentage of those viewers was pleased with what they saw, as I've seen a lot of people commenting on how few original games it will have at launch as well as the design of the console (I've also seen a lot that like the design). Just curious!
Some of the best selling movies, for example, are very unpopular but sold so many tickets because the previous one was so good.
