Yes, they confirmed till Feb 19, 2014 at 6:00pm, I assume Pacific Time.

Yup! Pacific.

I had PC version preordered for me and my wife, cancelled both the other day, played the beta on PC last night and don't regret cancelling.

The way the beta has been hyped. It looks like that 400k can happen soon. If only digital pre-orders were available on Xbox One then it would be even easier.

We will see what happens after the 14th with pre-orders. I think we will have a big bump.

Titanfall needs a Average of 42,318 a week to manage 400,000 Pre-orders. I think the Beta has hyped many, many people up. Next week we should see the results from this hype. This will cut it close, if the hype push's many out for a pre-order.

A little Anecdotal evidence here.

I just took 2 people to pre-order Titanfall and another was in there doing the same. Rayman Legends seems to be doing really good at my local gamestop. We also went to pick up 2 copies of Rayman Legends and bought out the last copies. This doesn't mean it's going to do great but could do a lot better then expected.

I'm going digital, and I imagine so are many others.

@ the 1:38:45 mark on the latest windows weekly show Daniel Rubino announces that the titan fall custom console is going to happen and will be announced soon. (he's an editor for a windows phone site)

It's looking more and more like your 400,000 prediction may come true!  Will be really interesting to see how this Beta spurs on sales.  People seemed to really like it and tell others.

Plus, hope they annouce some digital numbers. 

This might increase on Forza 5's penetration.

It could also have really good legs.  I think it will have good legs till another big shooter comes out.  Which is usually the fall.
