3.2 quad in stock right now. No displays though!
If talking about the USA refurb store.... gone.
The next Mac Pro isn't selling right now. Apple has pulled the current one from their store. So the
only way to buy a Mac Pro directly from Apple with normal warranty and eligible for AppleCare is through the refurb store.
This is same state the EU markets have been in for around 9 months. Same impact. Refurb store, where available, emptied as soon as any show up. [ If recall correctly there is some webservice that crawls the store and will email as soon as something shows up. ]
Once the new Mac Pro starts shipping, these refurb may stick around online for longer blocks of time.
