Windows Phone 8 development on Windows 7 - is it or will be possible? [closed]

Question

I was trying to install Windows Phone 8 SDK on my Windows 7 machine and it hit me with the 'supported only on Windows 8' message. I actually wanted to develop Phone 7.5 apps on Visual Studio 2012, impossible thing with the 7.1 SDK, so I thought 8 SDK will do the job.

As if it was not enough that the 8 SDK was controversial upon release, now that it's generally available, to me it seems like a horrible decision to make it available only for Windows 8, because in my humble opinion, no serious and sane developer will install Windows 8 ever, or at least in the near future, just because of the Metro UI.

So, anyone knows any workarounds for developing Windows Phone 8 on Windows 7, or at least develop for 7.5 but using Visual Studio 2012?
