Some Conclusions after a light sampling of the different Amazon threads over the past 2 - 3 week period (Switch games only):
1. NBA 2K19 will not likely see an increase over last year's sales performance (already evident from UK GFK data).
2. Fifa 19 on switch will not be as disappointing as I was thinking it might be a few weeks back, should see a bit of an increase over last year's performance (its already in the top 100 with about 10 days to go in most Amazon charts)
3. The switch's Q4 is shaping up nicely, Smash and Pokémon bundles are doing very well already on the charts and look like they will sell gangbusters
