Inter-brand support is more like a pipe dream than the actual future. There's more to closed designs than a given company wanting to force users to buy nothing but their own gear (although it is certainly a reason); a greater reason is that R&D is a legal minefield, what with so many patents and the risk or being sued left and right.
When there is a patent, the only way for company A to make its products work with those of company B is through licencing. And this depends on whether A sees any advantage, besides the monies coming from the licence, in giving B the opportunity to use its technology.
The problem is not technology, but lawyers, as usual. Thus, even though the technological milieu is in a permanent state of flux, making a decision based on speculation or hopes that this or that will become available is quite a bit of a gamble. It does happen every now and then, mind; there's the case of Profoto partnering up with Hensel and giving Hensel flashes the ability to use Profoto's radio triggering system. But whether Canon will open up to other companies, hmm, I wouldn't put any bets on that.
I just want to clarify two things: first, the 600EX is not a bad flash. It'll serve you well, whether you use it in manual or E-TTL. You're free to use Canon's own radio triggering and/or a 3rd party system. With 3rd party systems, you just have to make sure said system supports the unit AND ALL its features, lest you end up in the same situation I did with the Cactus. Now, I can only speak for PW's —as that is what I use and I'm not interested in switching to any other system simply because the PW's work for me and they're made in America—, and their page reports the 600EX as supported. Radios aside, the 600EX still supports the old infrared wireless system and it has full manual mode too. Do note that some of the newest and niftiest features only work with cameras released after AD 2012, so your current camera may or may not take advantage of them. B&H's video of the flashgun
is quite descriptive. Heh, you probably have watched it by now. One thing I do like about the Canon flash is that it can zoom up to 200mm, something the MeCablitz cannot do. Heck, you can even use it to trigger monolights (when you migrate to those later on) equipped with optical slaves by using a burst of light from the flash: no radios or infrared needed.
The second thing I want to clarify: I do not get kickbacks from Metz, Hensel, Manfrotto, Photek, or any other manufacturer; nor from B&H, Adorama, Vistek, or any other store. I make a living by taking photographs, not through reviews or affiliate programs. What I have advised to you is the product of my own field experience with the equipment; equipment that I purchased after doing extensive research (the manufacturer's web sites, product manuals and white papers, non-biased reviews from reputable sites, and yea comments from actual users), and by being burned now and then by a bad product. Other than the small satisfaction of having avoided you potential problems and frustration due to equipment of poor quality, I receive no recompense whatsoever if you end up purchasing what I suggested or not.

[...] Everyone else (like PocketWizard as well) are just using the optic wireless system and transferring that to radio.
You are describing the RadioPoppers, sir. The PocketWizard system does NOT use the infrared signals at all. If you took the trouble to examine a PocketWizard unit you would see that they have NO IR sensor! Please investigate before you make incorrect statements such as that one, and others you have made above, comments that come not out of actual knowledge of a given system or unit, but out of overt aversion for a particular German manufacturer.
