Is anyone else underwhelmed by the 13?

From what I gather the 13 has a few cosmetic changes, slightly bigger battery, and a heat sink. That to me smells a lot like a 12 but at a jacked up price. At the same time the 12 seems isn’t compatible with new accessories.

I have the 8 and was waiting to see whether I want to upgrade to the 12 or 13 but it seems that GoPro is selling a dolled up version of the 12 as a 13 and phasing out 12 from the new cool accessories (I was burned when I bought the 8 and they changed the factor on the 9). Now I’m just thinking I might as well just wait for the 14 to see if it will be an actual hardware upgrade rather than a firmware improvement. I have a feeling I’ll regret getting the 13.

Is anyone else in a similar boat or am I just expecting too much?
