Unless you're going to overclock it (which I'm not sure is possible, probably) you don't need a heat sink. It will throttle (reduce speed) if it gets hot. A heat sink keeps it from overheating so soon so it can run at full speed longer. If you run cpuminer (to mine Litecoin or Bitcoin) it will overheat a Pi very quickly and slow down, even without overclocking, because it's so CPU-intensive. You can run less threads to run cooler.
What I'd like to see is a massive heat sink that dwarfs the circuit board and becomes dominant, sort of like with Pentiums, could even have a fan. You'd mount the heat sink then bolt the Pi to it, probably with heat sink compound or a heat-conductive washer. The connectors and wires would go wherever they ended up. There could be such setups as aftermarket addons. I don't like that they continue to push the power connector to its limits instead of going to something else like a coaxial plug like the Rock64 uses. I'm not sure it it's still a microusb or not. But you can always power through the GPIO connector. And this uses _micro_ HDMI connectors, as opposed to the Zero which uses _mini_ or the earlier Pis which have just a regular HDMI. So if you have a slew of Pis and Zeros you need 2 adapters for video. GPIO pinout at https://www.element14.com/community/docs/DOC-92640/l/raspberry-pi-4-model-b-gpio-pinout-with-poe-header?ICID=rpimain-smartpanel-pi4doc I'm not sure how different it is. The Pi GPIO has gotten to be a defacto standard that other manufacturers also use. I see there are still multiple 5 volt and ground pins so they can be paralleled for more current capability. I welcome the 4 GB of RAM the most, I use 2 swap files and get tired of waiting for swapping and unswapping. Hopefully the ethernet is no longer tied to the USB. There is a new case and power supply, at least partly for the 2 micro-HDMIs. A Rock64 fits into a Pi case but the power connector is different so it needs some filing. The cases are sort of a nuisance because the wires dominate everything and are much heavier.
