SE V: Support for non-.bmp images?

[Noble713]

I know that SE4 used .bmp format because pretty much anyone has software that can edit them. However, they also take a RIDICULOUS amount of hard drive space. SEIV Gold + 4 mods (Proportions, Star Trek, B5, Star Wars Rebellion) eats up a hefty 1.34 GB.

So is there any word as to whether SE5 will be able to accept JPEG or GIF images? I'm sure that would cut the size of the game down considerably, by just converting any existing .bmp files to .jpg.
