Looks like Xbox Live Arcade decided to follow the Wii's example this week, adding both something old and something new to the mix this Wednesday with Buku Sudoku and the Atari classic Warlords.
Warlords (400 Microsoft points), like many arcade re-releases comes in both original and fancy form, with the extra room leftover from making the primitive graphics less primitive translated into places you can showcase your face or whatever other sections of your body you wish to share with the group during online multiplayer matches.
Then there's Buku Sudoku (800 Microsoft points), which I am very angry with and don't wish to discuss.
Both games should be available via Xbox Live early Wednesday morning.
