Based on the amount of issues I've seen with the Pi4 (heat, USB power delivery, USB power issue with GPIO) I am 1000% waiting for Pi 4.1 edition in 3 to 6 months.
Also, sadfly, I wouldn't use one without a fan, period.
And miss out on all the debugging action? I'm seriously enjoying my Pi 4 despite its initial issues. Minor issues that is. It's just so much more powerful than the Pi 3. Kodi has never been so responsive on my TV screen. It feels as if there's a full blown PC hiding behind the TV somewhere. My Pi 4 is not in a case yet and that's fine. That way there is no heat issue whatsoever. And no fan mind you, just a small heat sink on the SoC. USB power delivery is fine with an original RPi power source or any plain USB charger with high enough current output. I wouldn't want to use an expensive phone or laptop charger with it anyway. I'm patiently waiting for a good case to become available where I live. And for the time being I'd still pack my Pi 3 if I wanted to use Kodi on the road. Sure there are issues but simply don't expect to make full use of the hardware yet (such as running HDR 4K60 video) and just treat it as an overclocked Pi 3 for now. The rest of the awesomeness is on its way.
And by the way, if you have lots of H.265 material such as myself then the Pi 4 actually has less issues with heat than a Pi 3. The thermometer icon regularly popped up with my Pi 3. I have yet to see it with my Pi 4.
