Widescreen HD remasters of Saturn classic NiGHTS Into Dreams and Dreamcast platformer Sonic Adventure 2 are scheduled to hit the PlayStation Network today, costing £6.49 each. To get you in the mood, SEGA has released a retro-tastic launch trailer (which also reminds us that NiGHTS will include the Christmas content pack for free).

Xbox 360 owners will have to wait until Friday, with both titles setting you back 800 Microsoft Points apiece.
