well, im just assuming the worst so I can be pleasantly surprised if 5.2 is out early
If their plan still is to have the next patch out in about 2 months, it'll be on the PTR soon. And I don't mean Blizzard soon.
Just because a new raid is coming, does not make it 5.2. Just look at how many patches and releases were in 4.3.
Patch 4.3.0 29 November 2011
Three new 5-man Caverns of Time dungeons (End Time, Well of Eternity, and Hour of Twilight)
New Caverns of Time Dragon Soul raid
Darkmoon Faire island
Patch 4.3.0a 2 December 2011
Patch 4.3.2 31 Jan 2012
Patch 4.3.3 28 Feb 2012
Scroll of Resurrection system changes
Patch 4.3.4 17 Apr 2012
New Customer Support window UI
I would imagine we will get something more like 5.1.1 and it will cause mass panic and uproar on the forums.

We'll know what's in 5.2 soon.
Soon does in fact mean soon, meaning this month yet.
