Yes, Noragami is still ending with Volume 27
I've seen quite a bit of misinformation being thrown around that the article about Noragami ending that was released earlier this year was "misinterpreted" and that the fact that 107-2 is not going to be the final chapter is proof that it's not ending that soon. This is due to misunderstanding the release schedule.
Noragami is ending with volume 27, at the "end of 2023". This information is not in dispute.
What is in dispute is exactly how long volume 27 is going to be, which is what led to the original estimates of how many chapters are left.
Most volumes consist of four 44-page chapters, for a total page count of 176 pages plus table of contents, acknowledgements, 4-koma, etc.
Volume 1 was an exception. It only had 3 chapters, where chapter 1 was 68 pages, chapter 2 was 60 pages, and chapter 3 was 54 pages for a total of 182 pages. The standard 44-page count started with chapter 4.
Volume 27 will start with chapter 104. 104-106 were all the standard 44-page chapters. The first part of chapter 107 released yesterday was released as a 22-page segment, with 107-2 to be released on 9/6/23, and not be the final release (since there would have been an announcement if it was). This could mean:
Chapter 107 is the last chapter but, as is typical for final chapters, is longer than normal and will be released in 3-4 parts instead of 2.
Chapter 107 is not the last chapter, but rather chapter 108 is, and Volume 27 will have 5 chapters (come to think of it, 108 is an excellent number for the series to end on, because the number 108 is important in Eastern religions)
Some combination of both of the above is true, where 107 is 3 parts and 108 will get dropped all at once afterwards.
Regardless of the release schedule, which is the only unknown, the "end of 2023" end date means we have between 2 and 4 monthly releases left. We just don't know how many pages those releases are going to be or what chapter numbers are going to be associated with them.
