Hi sergey, As you mention VS2013... I got my upgrade license recently but had no time to test it yet. I could try a port to vs 2013 in February 2014. So we could actually skip VS 2012 and switch to VS2013 directly. And drop XP maybe in a release that comes in the second half of 2014. With asap I did not mean we should drop XP support immediately, but we can't support it forever and vs2012+ gives us very the chance to speed up blender significantly if we had the chance of carving out the VS2008 stuff and optimize the code for the new compilers.

It should be a clear for everyone process with defined release when we're dropping. Ideally it should be connected with switching to a new official compiler for windows. Meaning, when we're considering MSVC 2013 as a default to build blender on windows then we might stop maintaining old libraries and let XP support fade down naturally. As for dropping support of 32bit -- i don't see good reason for this just yet. It might be 2-3 people who supports libs on windows, but i only know one who supports all the libs libs on linux. It's not much of hassle if we update libs only when we need this (meaning not just to be on a leading edge with brand-new libs). Dropping 32bit windows builds would mean we're dropping atom support as well? It might be still useful to be able to run blender on a netbooks i'd say. Also, you might want to use PAE on 32bit platform because of some better load balance and so.
