DPreview general manager, Scott Evertt, said that DPreview will remain available and will be archived once DPreview shuts down. Here's Scotts message:
We've received a lot of questions about what's next for the site. We hear your concerns about losing the content that has been carefully curated over the years, and want to assure you that the content will remain available as an archive.
We've also heard that you need more time to access the site, so we're going to keep publishing some more stories while we work on archiving.
Thank you to this community and the support you've shown us over the years.
