Buy 6P now or wait till after holidays?

Intrigued by Google's Fi plan and the "pure" Android experience, I was looking to buy the 6P (the Pixel phones are just way too expensive for me. I can afford them, but for me I can't justify that much money for a phone). Currently have LG G3 on Sprint (purchased last year on sale for $.01!!!).

I was wondering if it's worth it to wait until after the holidays (price drop?) or doesn't it matter with the Google phones. Thank you for any help you can provide.

Almost forgot, I'm breaking my own rules with the 6P because I previously preferred replaceable batteries and an sd card option. If anyone has any feedback with the 6P regarding that I would appreciate it. Did it impact you at all? Thanks again...
