I just went there and have it on another tab and its there. Maybe they weredoing some updating or something.

Hmmm just had another look and it's still not there, I'm on the australian Dell page I might add. The R3 has also gone. Maybe site maintenance, like you suggested

I was on the USA site.  

Yeah, I already posted a topic about this. First, the regular version of the Area 51 vanished from the website. Then, there was a message saying the ALX Area 51 was unavailable. I had Dell call me, and I was told they're unavailable, and they were unsure as to if they were simply out of parts or they were designing a new version. They're suppose to give me a call again after they've talked to someone higher up who knows exactly what's going on.

I'll be keen to find out. My expected delivery date has updated a few times, status is still work in progress.

The new sandybridge enthusiast class is due to come out before the end of this year. Could have something to do with it.

I too have one on order, from the 29th Sept. I emailed the sales dept. and asked if the shipping date for my system would be affected, and was told no, I would still get my system by the expected shipping date (25th October)......I have my fingers crossed!!

Nice of them to mention the model is about to be replaced within a week of buying the area 51. I don't think the sales team are kept very up to date anyway.. oh well . Can't wait for mine to arrive. I will be keenly watching the dell website over the next few days.

Just got off the phone with Dell, apparently, the Area 51 is being replaced with a new model called Area 52, but she wasn't sure when it was coming out. Now I thought "Area 52" was just the name Alienware was using for it's promo tour?

It's gone from the Australian website though, so I'd guess OP is from Australia.
