Current size is HUGE and growing at a phenomenal speed.
Public IP networks...just look at ARIN, RIPE,etc and see how many IPs 
there are left.
Private networks and private IPs...well that is anyone's guess.

There are no estimates because everything changes rather fast and noone 
can keep up with all this stuff.
The only thing you could have a really good estimate are the resources 
used by your company and thats about it.
