MinecraftDev.exe is now done and it is called minecraft.exe

you cant use 1.6.1 in the normal exe unless you change the jar file

you can get the exe at www.mojang.com

you now get profiles and options

you can change the resolution and the game directory

you can change how much ram is allocated to the game

you can get all versions of minecraft from the very old versions til the newest

they stopped use of the old launcher :(
but theres no need to use it anyway
