Yes to Sins of a Solar Empire 2 please
Yup, I'm quietly optimistic too.
also would be nice to have Sins1 in 64bit meanwhile, since with horde fleets it crashes even with enable large address.
It's most likely not worth the developer's time in porting legacy code to a new(ish) architecture now that Sins 2 is in the pipeline. It would make far more sense to concentrate resources there rather than dust off old code and try and get it to build with a new compiler.
