According to a memo Sony recently distributed to its publishing partners, the hardware manufacturer plans to restore the PlayStation Store on May 24.
The document (via Gamasutra) claims that Sony is planning on rolling out two weekly content updates for the next fortnight, allowing it to offload its backlog as a result of the recent PSN outage.
“We thank you for your patience as we work to resume service of the PlayStation Store,” the memo states. “If there are concerns, we are willing to consider adjusting the release date of your content on this schedule. Adjustments will be made on a case by case basis.”
Apparently, the first update will go live on May 24, and includes content originally planned for April 26. The second update on May 27 will contain updates that had previously been planned for May 3. Further updates are also in the pipeline for May 31 and June 3.
After this is accomplished, Sony is expected to be up to date on all PS Store updates and the regular schedule will resume.
It’s worth noting the memo doesn’t give any mention as to how Sony plans on offering compensation for any losses developers may have incurred as a result of the downtime – assuming it's planning on doing so, that is.
