> They also switched from yearly to quarterly releases (for their Apps) which means they deliver a lot of features in a year.

Without commenting on whether this is true of Oracle, that conclusion doesn't inherently follow from the given. If I'm driving 60 miles per hour, then recalculate it in miles per minute, that doesn't actually mean I'm going faster. Oracle could easily be delivering 1/8 a year's worth of features in 1/4 a year due to release process overhead for all I'd know.
