64-bit?

[m^2]

Seeing that TC has gone 64-bit, will there be a 64-bit version of TCUP? I understand that all TC plugins need to be 64-bit too... what's happening on that horizon?

You noted the problem. Plugins. It will take a long time before 64-bit TC will have enough features to roughly offer what 32-bit does.

Near all computers purchased in previous and this year has 64 bit windows, even laptops. So we need TcUp in 64 bit too.

You're wrong. It's a fallacy that 64-bit OS needs 64-bit software.
Even Microsoft doesn't offer some of their programs in 64-bit because in that cases 32 bits work better. Visual Studio for example.
TC is one of programs that would indeed benefit from being 64-bit, but the benefit is rather low and a good majority of users would never notice any difference.
