Good news for the WineX fans. TransGaming has updated their site with this note:
TransGaming’s WineX 3.0 Preview Release 1 is available immediately and exclusively to TransGamers to download and install today. Some of the many new features include: preliminary support for games such as SimCity 4, BattleField 1942, Dungeon Siege, and Medal of Honor: Allied Assault. WineX 3.0 includes vastly improved DirectX 8 compatibility, and now has hardware vertex shader support for some of today’s hottest titles.
It may be important to note that a native MOH:AA client is in the works if you prefer that.
