Typically, I don't line up as a first implementer. But if I had the device under my fingertips, I most likely won't be aware of hidden or unsupported features. Apart from the zero power feature, everything in the device handbook looks similar to MAX II.
Actually having the DPLL option would open new applications for the device, so I'm seriously interested now. A recent update to my support request (from sunday) promises an early reply. I'll keep you informed. If anyone else got substantial news from Altera in the meantime, I would be glad to hear about.
Regards,
Frank
