No. I doubt it. I expect the M4's to be released sometime late next year (or early 2025). 8GB is still going to be enough for general office work (word processing/ writing letters, accessing websites, etc). Why? Look at the history of memory in Macs:
What was the default RAM in Macs, how long did it stay, and when did it change? For simplicity and ease of research, I’ll start from the Steve Jobs era, and I will only focus on consumer portables. All information from MacTracker

- 32MB. This was used in the iBook and iBook Special Edition in July, 1999 until it was discontinued in September, 2000. It lasted
14 months.
- 64MB. This was used in the Firewire iBooks from September 2000 until the Dual USB iBooks in October 2001. It lasted
13 months.
- 128MB. This was used in the late 2001 iBooks released in October 2001 through the iBook G4, discontinued in April, 2004. It lasted
32 months.
- 256MB. This was used in the Early 2004 iBook G4 released in April, 2004 through the late 2004 iBook G4 released in October 2004, sold until July, 2005. It lasted
15 months.
- 512MB. This was used from the Mid 2005 iBook G4 released in July, 2005, until the Mid 2007 MacBook, which was sold until November, 2007. It lasted
28 months.
- 1GB. This was used in the Late 2007 MacBook released on November, 2007 until the MacBook Late 2008, discontinued in January, 2009. It lasted
25 months.
- 2GB. This was used in the Late 2008 AL MacBook released on October, 2008, until the MacBook Air 11”, Mid 2011, which was discontinued n June, 2012. This lasted
44 months.
- 4GB. This was used in the MacBook Air 13”, Mid 2011 released in July, 2011 until the MacBook Air, 13” Early 2015, which was discontinued in June, 2017. This lasted for
71 months.
- 8GB. This was used as standard on MacBook Air, 2017, released on June, 2017 until now, in November, 2023.
77 months and counting.
Clearly, the amount of time machines stayed at 1GB was half what the time for 2GB, which was almost half of what 4GB. I expect 16GB to become standard in another 40 months (or about 4 years) or thereabouts, if trends continue.
