I think so. You know, Kodansha has spent time and money for the first two volumes, so I believe the intention is to release the entire manga.
They might be waiting for 30th anniversary in 2022 to continue or relaunch it (hopefully with new covers....god!
).
The covers.... the covers is the proof they didn't have this new edition ready to release it in 2020. The ice show poster didn't feature the Outers senshis and Chibiusa. If this new collection is called The Complete Colour Edition, that means it's the kanzenban full colour in ten volumes, one per senshi. That said, maybe Kodansha didn't have new illustrations of Uranus and company to use. Maybe the colouring process hadn't been finished yet back then. You know, it seems that the whole project wasn't polished and ready-to-serve.
Then, if we think about it, in the 20th anniversary we had the Kanzenban in Japan and the Shinshoban in the international market.
In the 25th, the Bunkoban was released only in Japan at the same time the Kanzenban was in the Int. market (plus digital edition globally).
Everything points to the Full colour being released in the 30th. If it were only digital I'd like them to release it internationally as well. But, oh well, business is business.
