One more spot of Destiny news for you tonight. It has been confirmed that if you buy either the Xbox 360 or the PlayStation 3 version of the game, you are going to be allowed to upgrade to either the PlayStation 4 or Xbox One version at no extra cost. Here is how you go about getting that free upgrade.
When I buy/redeem the Destiny Digital Base Game, Digital Guardian Edition, or Expansion Pass for PlayStation 3, how do I get the free PlayStation 4 version?

When you buy/redeem the Destiny Digital Base Game, Digital Guardian Edition, or Expansion Pass on or before January 15th, 2015, you can download the Playstation 4 version from the PlayStation Store for free by doing the following:

- Log into your PlayStation 4 using the same Sony Entertainment Network Account (PSN ID) used to buy/redeem the Destiny digital content on PlayStation 3.
- Navigate to the Destiny content page or search for the corresponding item you purchased previously on PlayStation 3.
- Add the item to your cart and complete the transaction.
- Wait for the download to complete.

The same applies for the Xbox One version of the game. There are a few additional details in the FAQ for the upgrade system, so be sure to check out the Destiny digital upgrade guide. It also explains what happens to your bonus content, and the fact that your stats and gear will safely make the transfer from last-gen to current-gen.
