This is just one more reason to follow the Prime Directive:

NEVER believe what ANYONE says about the future.

(and only half of what they say about today).

Most manufacturers (myself and probably you too) don't always deliver
what they promise when they promise it.  It's just a fact of life.  New
silicon is usually 3-6 months late.  If it's a totally new line, triple
that.  Documentation to follow.  If a design has a deadline, I never
consider ANY part that hasn't been on the market for several months.
Better to spend a few more bucks on something that you can build than
save money on something you can't!
