One can't implement overloading of the Zend Engine 2 in PHP4 so this is
not "the full package". And then, the most important feature of PDO is
that it's NOT WRITTEN IN PHP like any other database abstraction layer.
It's written in C for speed.

It will not fail because it will be the de-facto-standard for new
programmers. PHP tutorials will start containing PDO examples instead of
mysql_* examples. That's even more true because the mysql extension is
not included by default anymore.

This is true for the 10 percent of PHP programmers doing complicated
database stuff. PDO still is good for them because PDO explicitly makes
stuff unique to a particular DBMS available through its interface (the
doc is full of "this will only work for some engines"). The other 90
percent will be fine with what PDO has to offer.
