I have been using my 64bit cpu with Debian amd64 kernel since 2003, now when are we going to 128bit?
I bet this is going to be like when we upgraded to 32bit, and it seemed nobody wanted to stop using 16bit. Now that 32bit is on its way out, there will be complaining, just like before...
The market will simply stop selling 32bit until 64bit is the standard. But first, all 32bit systems will go on sale so they can get off the shelves to make room for the 64bit.
But look at the bright side. With many 32bit running together, you can have one nice system.
