The Great Loot Box Fire of '17 received as additional slosh of gasoline yesterday when Belgium announced that its Gaming Commission, which regulates gambling in the country, had begun an investigation into whether loot boxes in games like Star Wars Battlefront 2 and Overwatch constitute a form of gambling. The consequences of a "yes" decision are potentially enormous, which is why it's not at all surprising that Electronic Arts says "nuh uh." 

"Creating a fair and fun game experience is of critical importance to EA. The crate mechanics of Star Wars Battlefront 2 are not gambling," the company said in a statement sent to Gamespot. "A player’s ability to succeed in the game is not dependent on purchasing crates. Players can also earn crates through playing the game and not spending any money at all. Once obtained, players are always guaranteed to receive content that can be used in game."
