No, it’s not a Blu-ray/HD-DVD day (although I’ve just ordered the HD-DVD of Mallrats on eBay), but more a diversity within the Blu-ray branch.
Take a look:

Defiance / Sin City (2-Disc Ultimate Edition) / Terminator 2: Judgment Day (Skynet Edition)
Starts off with Defiance, a movie about how a group of Eastern European Jews, under Nazi reign in 1941, battle against their exterminators. It sounds like a cool flick with Daniel Craig and Liev Schreiber. It’s got a 1.85:1 aspect ratio and a DTS-HD Master Audio 5.1 English track. Sounds promising.
I’ve updated my previously Dutch Terminator 2 SteelBook by trading my disc for a UK one. Received it today with the Skynet Edition slipcover as well. It’s got the same specs as the Dutch disc: DTS-HD Master Audio 6.1 English audio, the three versions of the movie, same bonus content…
Last but not least, the Sin City 2-Blu-ray Ultimate Edition. It includes both the theatrical cut with a massive DTS-HD Master Audio 7.1 English track whilst the second disc includes the Director’s Recut with the four individual stories set apart with extended scenes.
