What we have learned from how 1C responds ( or not) to embarrassing questions should tell us were it is going...
In every "patch update" thread Luthier wrote, the 64 bits question has been raised from members witout any feedback from Luthier...No mention either in his 7 point steps toward technical glory about 64 bits...Never heard anything from Oleg nor Luthier about 64 bits...But is it really essential for future developpement ?
If it is, it would have been a risky decision from 1C not to include 64 bits in the code ...

Salute !
