It is growing steadily. The comparison between baseball and soccer is unfair imho - both sports have a completely different history and organization. Just looking at the organizational side: soccer governing body FIFA accomodates it's calendar for international tournaments and competitions (like the World Cup) and national leagues are obliged to follow. When something takes place that doesn't fit in to the set scheme (like the upcoming Olympics) it creates all sorts of problems - clubs are reluctant to release players for the Olympics and when they have very little choice (i.e. in countries that have qualified) games have to be resheduled for teams that will be missing several players. Just to give you an example: Belgium have qualified, and the big traditional clubs here have already stated they will demand that their games during the Olympics be resheduled (creating all sorts of problems because those clubs are also the ones that have qualified for the Champion's League end UEFA Cup competitions). On the other hand, foreign clubs don't want to release their Belgian internationals for the Olympics (e.g. Hamburg with Vincent Kompany). In international soccer, FIFA rules and the national leagues have to follow, although it must be said that clubs are gaining more influence and power, as is now obvious with the Olympics, where FIFA rules don't oblige them to release players. Baseball is organized in a completely different way - MLB rules and international bodies have very little power. And as long as MLB does not accomodate for the international game, you'll be stuck with a WBC in it's present form. On a side note, there are actually two WBC's: there the Classic (1 edition - organized by MLB/MLBPA) and the Cup (37 editions - organized by IBAF). This doesn't stop baseball from becoming more and more international, just look at the diversity of players: a small country like the Netherlands currently has 42 players playing pro ball in the US (list - yes, I know, a lot of them are from Curaçao, but they are still Dutch nationals).
