It looks like Barnes & Noble decided to bump the ship date up a couple weeks.
The Nook Glow, which according to the website is supposed to ship 7 May, is coming a lot sooner than expected. B&N is now sending out emails saying the Nook Glow is due to ship today. One of my readers reported getting one, and then just a few minutes ago I got one.
My order is expected to ship out today. That would tend to make last night's visit to see one in a B&N store redundant, but I thought it was worth it. I might not have ordered one without that visit.
