Long term: yes. Short term: probably not. You might see a sale from a particular carrier on the S4, but considering the S5 isn't coming out until April, and everyone else will have the same idea you have, I wouldn't expect any massive price drop soon. The S3 didn't universally drop in price until months after the S4 came out. If you want a S4 cheap then get it online or wait for a promotion from your carrier.
