well, VSL and NI are two seperate companies ... though you have seen VI/VE versions labeled as public beta at VSL from time to time this is not to become a rule ...
64bit VI/VE versions are on the schedule (and maybe it will be decided to publish a not 100% perfect version as public beta) but for MIR there isn't even a public beta available for windows ;-) so lets do things step by step ... and not cluck too much about unlayed eggs.
