There aren't any games I'm price watching. I'm waiting for some deals on some computer hardware though, either new cpu/ram/motherboard and videocard. Maybe even monitor but thats last on the list.
Mostly need a new cpu. Still using an i7 4770k cpu and time to upgrade this year or early next year. 4 core will be completely useless next year when the new consoles come out which will all be using at least 8 core/16 threads.
I'd definitely wait. Next Intel lineup is expected in early 2020. The much cheaper i5 this time around is going to be 6 core/12 thread, and the i7 will be 8/16. The i9 will be 10/20. But, all processors should come down in price pretty well, too.
