Windows 8 Codename Midori

What Windows 8 Codename Midori is aimed to rebuild entirely Windows, it will be goodbye to NT kernel? This will not be programmed in C / C + + code but in mixed as C #, F #, etc
Therefore for the time being "Midori" will make reference to Windows 8 when used in many articles and of course rumors that should start appearing after Windows 7.
I think that windows 7 is the last of the x86 32 bit operatings.
