Worth upgrading from a 22 Ultra?

I've been reading a lot of reviews and a lot of people are complaining that the 25 is not that big of a leap forward. Same processor as the previous model no real new improvements except for the camera, and they downgraded the S-Pen functionality.

That being said I have a 22 Ultra with $68 left to pay off. My provider just sent me a promo for a $1,200 rebate if I upgrade. Would I be a damn fool not to? I'm happy with my 22 Ultra and the battery is still in pretty damn good condition. I pull the trigger or wait another 9 months for the next model?

Thanks in advance.
