It sounds like PDF can do everything that EPS does, may be a little

PDF is built around EPS and contains things that EPS doesn't, because
they don't make sense in all contexts that EPS is used for. Also
remember that EPS (Encapsulated PostScript) is a way of, well,
encapsulating PostScript commands. EPS and PS will not die soon, or
perhaps ever.
In EPS we have issues with eps font (we have to have eps font
installed), does PDF has the same problem?
Most likely.
We can have high quality PDF preview without creating separate preview
pic like EPS.
Most importantly you do not have to know any language (like post
script) to create PDF where creating eps is very tedious work.
In many cases, it's much faster to draw a simple EPS preview bitmap
than it is to render a complicated PDF, such as in a page layout
document that might have 100 placed files. Blitting 100 EPS previews is
much faster than rasterizing 100 PDFs. (Yeah, you can cache the
rendering PDFs beforehand.)
There are also many different ways in which each file format can be
used. These days there are lots and lots of people that think PDF is
the end-all be-all format to use for every single occasion. That is
wrong. If you don't need any of the features that PDF adds over EPS,
then EPS should be used. But if your target audience for the files is
for people to look at on a computer with only a simple image viewer,
and possibly print, then PDF is easier to use for the end user. Also,
if your images will contain nothing more than a bitmap, why go to the
extra expense of processing time to embed it into an EPS or PDF when
you could more easily use a bitmap format such as TIFF or JPG?
Final output devices also determine which one you should use. Some
image setters and presses don't handle PDF. Our product (MultiAd
Creator) is used mainly in the newspaper industry, and you should see
some of the hoops our users go through to get data to their output
devices (export EPS, distill with Acrobat, etc).
