From the late & wrong category:
I tried to pick up my DS Lite at Sears on Irving Park Rd this weekend. I had the "Ready to pick up email". I got the "Sorry, but the DS Lite has been cancelled, recalled, not yet for sale, on hold, and doesn't exist" line from the Sears rep. Well, at least come June 11th, I'll definitely have one waiting for me to pick up.
I also stopped by my local GameCrazy and the manager there said Nintendo didn't send them any Lites yet because they know "we'll sell them early and break the street date". All 25 of their first shipment has been paid for already, but he said they are getting another shipment Monday and Tuesday of at least 50 more each time.
On a different note, he also said Nintendo is looking for a lot of retail support for the Wii, so they are shipping as many Lites as the stores can handle. I'm guessing to build some loyalty so when the Wii comes out, stores will push that as much as they do the DS Lite.
