Normally I'd leave semi-well-meaning guesswork in the MoP thread alone, but your post formatting is ugly, and it's whiny to boot. You're in a beta; count your lucky stars that you get to test the stuff, and don't complain about lack of addons, as that adds nothing to any discussion anywhere. Please write using paragraphs, as they were invented for a reason. Heck, you might even try one of those fancy bullet lists when appropriate. Don't use smilies as punctuation.
Also, as guesswork goes, this is pretty weak. You provide no evidence other than a gut feeling and some frantically waving hands, particularly regarding the hard cast of Pyroblast, though scarcely isolated to that one topic. If you want to go on intuition, there are plenty of sites where you may post that. Now, and especially once we're out of beta testing, we'll require evidence - sims, theorycrafting, math, etc. before you post here.

*Depending on current talents
The rotation may seem rather simple, there are a few finer details that make the spec more complex and dynamic. True skill and mastery of the fire spec will be elicited by how players handle the Inferno Blast 8 second CD and utilize it to create a large ignite for Combustion. I'm am currently unsure of what the best method for doing this is, but I have a theory:
While one crit has landed on the target and Inferno Blast is off CD, begin casting a Pyroblast (hard casting). Then use Inferno Blast to initiate the second crit which will land before the Pyroblast. Then you can cast the instant cast Pyroblast! right after. The end result is two Pyroblasts within 2 seconds that will hopefully yield a large ignite for Combustion. In the best case scenario, if both Pyroblasts Crit you will get a third Hot Streak proc and will be able to cast a third Pyroblast! at the target before Ignite Ticks.
Feel free to add in your thoughts.
From what little testing I did, intuitively I would say single target fire rotation will be something like...
Cast Fireballs till you get crit (You are chain casting so before you get notified that you critted you will be half way though the next Fireball cast)
As soon as Fireball starts flying you cast Inferno blast and proc instant Pyro
Not sure if that is what you meant, sorry if I just repeated it. With recent Inferno damage nerf I am not sure if this will be better then just chain casting Fireballs and not forcing instant Pyro proc with Inferno blast.
Concerning preparing for Combustion, I agree with you only disagree with stopping mid cast Fireball (as you are chain casting) to hard cast Pyro. First it might be quite hard to do as you want to be far away from boss, and secondly it might be DPS loss.
No addons on Beta make me sad panda, have to get numbers from combat log
