April 5, in fact
Guilty Gear Xrd: Revelator is coming west in June, but you’ll get a chance to try the demo out before then. Aksys Games has announced that the demo (which is a pre-order bonus) will hit on April 5. It’ll feature three new characters (Jack-O, Jam, and Johnny) and multiple modes.
It sucks that people will have to pay all over again for this upgrade (I really hope Capcom follows through with Street Fighter V and keeps it as one SKU), but Xrd was so fantastic that it makes the wound a bit less deep.
