Where are all these "I want it all free!!!" people coming from? D* is giving away ST, $100 online rebate, $50 giftcard, free HD for 3 months and free installation and it's still not enough? Damn.
Yes, D* is going to raise the HD price by $5 for all the extra channels they are adding. It'll cost $15 a month, which is still $5 a month cheaper than E*. By the end of October, D* will have 2x the amount of HD that E* has.
If you are switching mainly for ST, understand that next year, before your contract is up whether you get a free HD-DVR or not, you are going to have to pay $350 to get ST in HD. If you are worried about D* raising their prices $5 to offer 70-100 channels of HD, then maybe you don't really want to switch.
