Honestly doesn't sound like it this time.
APZonerunner, who gets the hot insider news from time to time regarding all things S-E, said the other day that they really have nothing set aside in their schedule for 'surprises'.
The only exception would be a FFXIV-E3 2010 style reveal. Apparently that's one of the rare things they kept completely under-wraps.
Still, all signs point to "please don't look forward to it".
Right. Nothing has changed on that front either.
