I know that VBA is still alive in Office 2007 and is reportedly (depending
upon which report you read) going to be supported for awhile. I love VBA, but
apparently VBA is going to be phased out. My feeling is that it is best to
get ahead of the game, welcome the change (and hopefully, improvements) and
begin learning the new thing.

So my question is, what is the new language that will replace VBA?

XML? VSTO? VSTA? I've heard and seen all these mentioned. Are there others I
don't know about?

What is the difference between them and what language should we really start
learning? What language will come incorporated into Office (as does VBA now)
that doesn't require another cash outlay of hundreds or thousands of dollars?

Any help or guidance on this would be greatly appreciated.

Thanks in advance for your assistance.
