Should i upgrade to the iphone 5? - 2

Currently i have the iphone 4S.
I'm going on a case spree but if i upgraded then the cases would no longer fit then a waste of money, what about the iphone 5s or iphone 6… Should i wait till then? Or should i just go on a case spree for my current iphone.

Wait for iPhone 5S

Wait till the iPhone 6 because it'll have better updates but you'll just hav to wait longer cause you save about 800 bucks cause if you wanna get the iPhone 5 then 6 when that comes out your just wasting money for a year or 2 and if you look on eBay or something you might find something there

I've got friends that have issues with their iPhone 5 and have had many people recommend getting the 4S over the 5, so I'd wait til later in the year when the 5S or 6 comes out
