No, Win x64 uses a so called LLP64 data modell
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/win64/win64/abstract_data_models.asp).
It can be assumed that Delphi for 64 bit will follow this which means
that only pointers will change their size to 64 bit.

With proper compiler warnings this causes usually no problems. Even big
applications with hundred thousands of lines of code can be ported
within a few hours.
