Is there any difference between different language versions of Windows 7 Ultimate? If I understand correctly, regardless of whatever language version I'll buy, I can change language after installation.
So my conclusion is that the different language versions are just DVDs preloaded with a specific language pack. Is this correct?
Yes that correct, although the install routines clearly must be slightly different.
There is an underlying language-neutral OS, and then the Language Pack is installed on top of that. This can be seen clearly by the diagrams in the following Microsoft developer's link:

This link also has a very nice description of the install differences between English and Chinese:
"the only difference is only in a different language pack installation files for English version of Windows 7, the first installation is x86_Microsoft-Windows-Foundation-Package_6.1.7600. 16385 base package, then install x86_Microsoft-Windows-Client-LanguagePack-Package_ 6.1.7600.16385_en-US language pack
For the Chinese version of Windows 7, the first installation is x86_Microsoft-Windows-Foundation-Package_6.1.7600. 16385 base package, then install x86_Microsoft-Windows-Client-LanguagePack-Package_ 6.1.7600.16385_zh-CN language pack"
This is correct, it is the standard pre-loaded language for the software, you can download new langauge packs or just change it from within the pre-loaded menu
