No, they will remand the cases that are in question to lower courts for review that will no longer include the "two part" test and will instead subject them to the history and tradition test outlined in the Bruen decision.
This is quite possibly the strongest language that could have been used. It is an incalculable boon that has changed the 2A fight overnight and will entirely reframe how legal challenges can and will be mounted against infringements. I don't think anybody expected this, at most even the strongest optimists were expecting Thomas to apply strict scrutiny in a limited fashion. This decision doesn't invalidate much outside of the shall / may issue carry permit debate (and half of the states are now constitutional carry anyway) but the implications of the changes to review for gun laws are absolutely immense. For an idea of what applies to "history and tradition", a 100 year old plus New York State law failed the history part and resulted in this ruling, so tards can't just say an AWB happened 30 years ago so it's historical now. I'm sure a few shitbag district court judges will try and squeak that one through, but the decision was extremely sternly worded and doesn't really leave much ambiguity out there.
It is likely to become a component in anti-AWB cases, mag ban cases, and hopefully some wily attorney can fashion it into an assault on overly restrictive import bans (but that's a pipe dream, just one I'd like to see).
