It is indeed 32GB.

But I doubt anyone but avid collectors would fill that all up.

If you buy retail games instead of digital (and dont plan to use music/videos/photos) on the memory card - what would be the best size?

Also how big are save files (average size) ;o?

save files are about 20 kb , they're small. games like fire emblem is nearly 2 gb , mario 3D Land is 1 GB. 

Edit : nope I confused "Blocks" with MBs never mind.
