Google likely to sell additional space for GMail?

Sergey Brin is rumored to have said that Google might start offering additional space for GMail users in lines of Picasa.

Picasa, Google's photo-hosting service charges $25 annually for 6.25 gigabytes and $500 annually for 250 gigabytes.

This would be good news to a whole lotta people who store a lot of data online, like me :)
