Touching the cracks between keys on the rMBP is like touching the inside of a volcano

If the base of the computer gets hot, it takes just a smidgen of common sense to figure out that the keyboard will also get hot, as heat radiates in all directions and heat rises.

Except on all my previous MacBooks the keyboard NEVER got super hot to touch. It only happens on the RMBP for me.

And frankly your common sense actually makes no sense. Why would the brand new cooling system in the RMBP (or any cooling system) actually allow heat to rise? You seriously think the inside of the MacBook allows heat to do its natural thing and spread in all directions? Lol.

Thats almost as dumb as saying "oh you got light bleeding issues? Well light travels in all directions from the source so it just takes a smidgen of common sense to figure out that it should be coming out the sides of your screen too"

I think he was just saying that if the bottom gets hot, the top will probably get warm too due to thermal conduction of the case elements. While the fans move the air out of the machine, the fans themselves as well as everything along the air path will also get warm. Those components then radiate heat to adjacent components. The cooling system in the RMBP isn't exempt to the laws of physics.
 
So will Zephyr 2 actually help with the heat around the cracks of the keyboard? Or am I screwed?

Whether it gets hot or not is dependent on how much workload you put on the system and how hot the internals get.

The new cooling system doesn't eliminate heat or the possibility that temps could get very high. Again, it depends on the workload on the system.

Yes, because there is no heat shield inside Macs that prevents heat from radiating in all directions. Macs don't violate the laws of nature.

Light doesn't travel though opaque objects. Are they not teaching basic science in schools anymore?

I still have the zephyr 1. It didn't do much good because it has 1 tiny puny fan. The design looked pretty but I produced more airflow by blowing under my laptop. If the zephyr 2 have just one fan again it probably won't be as good as the original. The design on the new one looks like the fan is enclosed in a tube? I am using one from cool master now and honestly it doesn't provide any jaw dropping results. There is plenty of airflow but it's still warm-hot to touch under full load. I get the same results propping a book underneath the rMBP vs cool master cooling fan.

When you play games it's gonna get hot. Physics and stuff. When you are not playing games the keyboard will be relatively cool to the touch or at least not very noticeable. Also depending on what you are doing. If it is majorly hot all the time get an application to monitor the heat and report back. You may have a Mac with faulty cooling system (either thermal paste, fans, etc) My 2012 2.6GHz cMBP is the coolest running Macbook I have ever used for long periods. I have tried all of them from Core Duo to rMBP. The rMBP was also a 2.6 and stayed cool for at least the 3 hours of building and heavy installation, restart, and indexing I put it though. Very cool. Like I actually noticed how cool vs. the rest and how long I would wait before feeling like I could close the lid safely.
 
I am honestly surprised by the number of people getting this machine for gaming. Apple should pay more attention to this audience.

Damn its hot. This is my first Macbook Pro, are they usually like this? This is with running Ultrafan by the way. It's uncomfortable

I was trying to run the Witcher 1 on Mac OSX ML.

The Retina Macbook Pro is the hottest Macbook Pro I've ever used, but it appears to be normal.
 
^^

1st gen were hot! The rmbp is no where near that temp.
My Air gets hot but it is more comfortable to "touch".
