DirecTV HD question?


I am thinking of buying a new HD rear projection television. If I did this I would probably want to upgrade my DirecTV service to include HD programming which would require me to change my round dish to an oval dish with a triple LNB. However, I recently heard that DirecTV is planning to launch a couple of new satellites in the next year or so. Would this mean that the triple LNB oval dish would have to come down in a year or so and be replaced with some new bigger dish with the capability of receiving signals from four or five different satellites?

Just read the short article in The Perfect Vision. Doesn't look like this would be the right time to upgrade to DirecTV HD. I am not interested in putting a new dish up in 6-12 months or taking the risk of having to trash a $1000 HD TIVO DVR box.
I am upgrading the DirectTV HD this week and will use my current SD Tivo but be able to watch HD programming as well. I figure most HD watching will be live sports and movies so the lack of Tivo for HD for a while should be tolerable. I think the feature I will miss the most is the back button. I wish I could have it for everyday conversation.
I get it now--duh// If you want the newer impeg 4 ; --yes--you will have to change out the dish and receiver. But the old stuff will still get what you have now.
I saw the Perfect Vision article too, and have up graded to DirecTV's HD service for my new plasma. It's great by the way, just not extensive. According to DirecTV, (I asked several different people at different levels)they will be launching 3 sat.s this year and didn't think it would require another dish if you have the 3lnb dish now. I know how this stuff goes, but maybe the 3 lnb will handle it.
