You don't have to wait until the fall to find out what the Ryzen 7000 will be like, as the company has unintentionally provided clues of its own. There was a list of early Ryzen 7000 processor models on the resource page, but they have since removed it. The 7900X and 7950X are two of the higher end chips that are the focus. It's not shocking that there's no Ryzen 3 chips, it's just that they're not.
Technical details were not included in the list. The 16-core CPUs that was shown in the Computex demo was a 5.5 GHz model. That might be the case. The 7000 series will be based on a new Zen 4 architecture that delivers twice the Level 2 cache per core, boost speeds above 5 GHz, and support for technologies likeDDR5 memory. If you want to make the leap, you will need an AM5- compatible board.
It's not clear when or how much the desktop line will cost. If you're hoping for a high-end laptop, you won't be able to get it until at least 2020. The tease gives you an idea of what to expect when the game is released. You can plan your upgrade according to the product strategy of the company.
