Any other con which may effect daily usage. Also, there are rumors of s9 releasing early. Will it be a wise choice to wait a bit more?
The waiting game will go on & on, there's new flagship every 6 months nowadays. S9 should come out to market in March even if it gets shown at CES. Also due to iPhone X every manufacturer would be interested in increasing price of their flagships. I won't be surprised if S9 launches for 60k+, in fact I expect that from Samsung. So if you are ok buying the phone in March/April for 60k+, gladly wait.
Personally the only issue I have with S8 is some edge touches which rarely happens but usually it happens when I use phone with one hand & try to select something at other side (say I'm using my phone with right hand & try to select something at left side of display with my right thumb). Otherwise its a great phone, but not VFM considering India's pricing. G6 & OP 5T seem more VFM, but those have some disadvantages compared to S8 for sure.
