I don't think so. I think they have planned this year long drought all along to "rest the franchise". It allows them ample time to build anticipation, gauge feedback and positivity around the brand and to understand the general discourse around their property. The Star Wars brand goes away for a while, the toys, shirts, and hats all leave the shelves and everyone starts to yearn for new content.
I would not be shocked in the least if we see several more of these resting periods, particularly after the failure of Solo. In fact, I believe they released Solo when they did to give a full year cycle between the release of Solo and the marketing for EP IX. In hindsight I think they know the mistake there is not releasing the movie, but releasing it in the fatigue window of Ep VIII.
