No, APIs will function as before, backwards compatibility will be
maintained. But Excel will look and feel very different. See

Will the Excel VBA of Office 2007 that ships with Windows Vista at the end
of the year be very different ?

Will all that we know and use today become obsolete ? For example, all the
API calls to libraries such as user32 will become obsolete as such
libraries
will be replaced by something else ?
