I think C++ pointers being 64 bit will stick with us forever, unless some fundamental paradigm shift happens in what C++ is used for. I also think the size of short, int, long long, float and double will not change anymore, ever. The reasons we had for changes in the past will not happen anymore from now on, and the cost of changes only increases over time. We might see the sizes (and IEEE-754 floats) be officially standardized at some point, like twos complement is standardized now.
