**Update- Limited Edition FAQ added**
The Limited Edition announcement raised some questions and created some discussion across the interwebs so here is a short FAQ to help answer questions we've seen by the community:
Limited Edition FAQ
Do I have to pay extra for the Limited Edition? No, it's the same price as the Standard Edition, just limited in quantity.
Do I have to reserve / pre-order to get the Limited Edition? No, but that's the safest way to ensure you get one since there will be a limited supply.
Can I get the unlocks featured in the Limited Edition if I miss out and can only get the Standard Edition? Yes, won't have the same day 1 advantage. You'll have to play through game and get the unlocks the standard way.
Where can I get the Limited Edition? We intend to sell it at as many retailers as possible, but it depends on where you live and how much your retailer wants to stock up. Once they're sold out, only the Standard Edition will be available.
Why don't I see the Limited Edition showing up at my favorite online retailer? It's up in some place like EA.com and will start to appear everywhere else. This is a busy time of the year and retailers are working hard to get this in place and it will be available both online and in-store.
Is the Limited Edition available on all three platforms? Yes: PC, PS3 and X360.
Will there be a Beta or Demo before the game comes out? Stay tuned to the blog or follow us on Twitter for future developments on all things Battlefield Bad Company 2.
