Are there any new smartphones coming out that are more modern than the Samsung Galaxy 4S?
I'm going to get a new phone but I don't want to buy one then a better one comes out next week.

Yes, but not for a while.

That won't literally happen. But this isn't a game you can win :) there will always be bigger, brighter, shinier phones popping up in the future. You could ask yourself the question: "can I see myself using this for 2 years?" If the answer is yes, go for it.
I have had the S4 since july, it is one of the best smartphones i have ever had, but as has been said something shinier and more glittery will be along in the future. The S4 is an amazing phone.
