I'll surely keep my iPhone 4.
The i5 is definitely going to be fine but I think buying the i4 was a good choice for everyone. It looks super cool, its display is beautiful, and the OS works like a charm. Why should I change it after just 1 year?
And it's good to feel that you spent your money for something which is good enough for at least 2 years.
So when I'm buying the iPhone 6, I can have a pleasent feeling that my good, "old" iPhone 4 served well.
