when the new Mac arrives, use setup assistant rather than migration assistant.

Where is this, and how can it help me fast restore my whole previous setup-ed system, without the osx versions problem?

I want to transfer everything in my new mac but I want my new mac to have the 10.6.7 new mbp-specific osx version! That's all! Not the generic 10.6.7 osx version of my current mbp.

Setup Assistant

Usually, the best way is to use Setup Assistant, when you start up your new Mac. It will set the new Mac up just like the old one: all configuration, settings, users and data, and all applications (except newer versions already installed).
You can choose to omit some categories, but you can’t "pick and choose" within those categories.
For details and instructions, see Using Setup Assistant.
You may be able to use Migration Assistant instead, but that can cause some problems, especially permissions problems with files already on other drives, including backups.
This links to:
Setup Assistant is designed to transfer all or selected things from one Mac, to set up a new Mac just like the old one.
Migration Assistant is used primarily to transfer user account(s) and perhaps other things, from one Mac or it's backups, adding them to a Mac that's already set up.

In other words, opening the new Mac the first time and starting it up and having your old MBP connected via Target Disk Mode or Ethernet cable or having the old MBP's HDD connected to the new Mac in an USB enclosure, will ensure, that you can use Setup Assistant and transferring all your data is possible. When you then boot your new MBP and run Software Update, you can see the 10.6.7 update specific to the new 2011 MBPs.
 
simsaladimbamba thanks for the guides.
Can I choose in setup assistant, to omit the upgrade of osx files?
I do not want the update to 10.6.7 through setup assistant.
I will update it manually on my own, downloading the 10.6.7 which is specific for the new mbps.
But, can I do it?

Your PERSONAL DATA will be transferred during the use of Setup Assistant.
The OS will be left untouched.
And the Setup Assistant can be found during the first startup of the Mac, when it asks you if you want to transfer data from another Mac.
Please read the links Jolly Giant provided and I just quoted.
Btw, you make it sound really complicated, but it is quite simple,
