With the iPad 2's specs (2x CPU, 9x GPU) Games and Apps will be MUCH bigger than the original..
We will probably see most games hit the 1GB range, and even more powerful games max out to 1.5GB.
If I were to get the 16GB iPad 2, I would only be able to fit all of my music (4GB)
and 5-10 GOOD quality iPad 2 games..

Developers are already releasing iPad 2 geared programs. Infinity Blade itself is half of a GB large. I think when Real Racing HD is re-released this week, it will be about the same size as well. I'd go with the 32GB to make up for some of these larger programs we will be seeing.
