What's about DDR3 16Gb PC1600 modules

What do you mean? Will 16Gb modules be available for MacBook pro's ? Some people say "keep dreaming" other people say they will come.

I ask, because the specs from Intel define the max. memory with 32Gb depending on memory type.

Intel Core i7-3720QM

What's your opinion or better what's your knowledge about this?

Thanks a lot for input!
