If so, consider saving $700 ( 2k - 1.3k ) and getting a 70-200 ƒ4 IS now ( lighter, better IS, and better IQ relative to the ƒ2.8 ). Come Summer, sell your 50D for >$300 and buy a 7D ( better focus, higher usable iso, and higher frame rate )
Is the 7D ƒ4 IS combo equivalent to the 50D ƒ2.8 IS combo - nope. For starters you won't have the cross AF bump from ƒ2.8 glass. However, you'll have a 7D ( very usable 6400 iso ) with 17-55 ƒ2.8 IS and 70-200 ƒ4 IS!
Maybe the 60D will be in the $1400 ball park come August and you can opt to keep your 50D. Nothing quite like having two lenses to shoot without swapping them - mount the 17-55 ƒ2.8 IS on the 50D and the 70-200 ƒ4.0 IS on the 60D.
