I didn't say they will use the old client. I was just wondering where people are getting the "LUL 480p resolution", "doesn't work on modern OS" and "does not work on current DirectX" from, because it's exactly the opposite - I played on Win7 x64, 1440p, DX11 with the 1.12.1 client just fine, connecting to a private server.
And then you came, babbling something about a re-worked 64bit client.
