Plans for OCE started before that are were still pushed back due to product shortages. Plans for a more immediate solution (they apparently had plans for some of this for 7.0 or post 7.0) to the rest of the data centers started the moment the un predictable influx of players came. Until that point, what they had was sufficient to handle the slow and rather predictable growth of players. You cannot expect a company to predict the unpredictable and purchase outside of need or planned upgrade.
