Should i upgrade from iphone 6 to the new iphone?

I've had my 6 for 3 years and it still works ok, the battery just dies quickly. Should i upgrade to the new iphone for $1000? It's the first significant design change since the 6.

As far as the price, lets see what it ends up being.
As far as purchasing, same answer, though it is looking very promising.

Could also look to the 7s/7s Plus if the 8 is too pricey.

Yes
