This certainly would seem to be the next logical move for the prestige journals. However, in the long term I think this decision to provide open access to the research allows new journals to compete on a more even footing, especially with the emergence of publishing and peer review services like Scholastica. Over time, a thoughtfully curated journal with advantages in speed, cost, editorial focus, peer review process, etc. may be able to overcome the journals whose advantage lie primarily in prestige & gate-keeping.
