If you're in North America, you can now pre-order the Day 1 Digital
version of Grand Theft Auto V
from the PlayStation Network. Pre-ordering this also gives you access to the Atomic Blimp. Those in Europe can pre-order the Day 1 Digital
version starting on Friday.
As an additional bonus, Day 1 Digital
pre-orders will also receive an exclusive PS3 theme
along with discounts on any Rockstar full game title
on PSN (prices vary by territory).
On the Xbox side, Rockstar says there won't be a download the first day but should be one in the future:
For those asking about digital pre-orders on Xbox LIVE, the Xbox 360 Games on Demand service does not offer the ability to pre-order games or make them available on launch day. That being said, we will be making GTAV available via Games on Demand as soon as it's technically feasible and permitted by Microsoft.
