I just ordered the 70-200 2.8 IS II. This combined with my 17-55 2.8 should satisfy my lens/gear needs for a long time. At least that is what I was telling myself when I hit the "Purchase" button.

Except maybe just a monopod to shoot my 5-year-old doing soccer.

And maybe just a 1.8 nifty 50 for playing with.

And I am just assuming my existing backpack will fit this beast...
