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.

I would imagine we will get something more like 5.1.1 and it will cause mass panic and uproar on the forums.
It's been confirmed that 5.2 will bring a new raid. What you listed were minor patches.

I don't think you understood the concept Blizzard is going for in Mists. 5.1 was not a major patch. There was no new raid in it. The release of Mists was in September. That's almost 3 months now. The plan is to alternate between patches that add little things like daily quests and patches that introduce a new raid tier. The plan is to have 2 months between patches. If that'll work is a different thing, but that's the general plan. 5.2 will not hit as late as april or may.
We'll know what's in 5.2 soon.
Soon does in fact mean soon, meaning this month yet.
