Yea only one OTA tuner per Hopper. But keep in mind the unit has several USB ports. Maybe in a couple years they will be cool enough to add the option for a 2nd OTA tuner. Matter fact, they wouldn't have to have it on a 2nd USB port. There are already dual tuner USB OTA tuners on the market. All they'd have to do is release a dual tuner on single USB device. You can add multiple hard drives from what I can tell, so why not a 2nd tuner. Unless they didn't put enough processing power into the unit to handle another incoming data stream.
Personally, I was actually disappointed that they didn't add a 4th tuner Satellite tuner. I actually record 6 late night shows each night, then set them to only store 5 as the limit. Then I go thru the info on them to see if there are guests I want to watch or not.
I also hope they upgrade to 4TB drives. Since the reserve too much for Primetime anytime and PPV content I think it would be nice to have the extra. I have an external drive attached to mine, but I still don't like their interface of having to go to the separate menu, and when you finish a show, it doesn't return to the external device DVR list.
A few other things:
I'm still disappointed that they didn't put enough processing power in the unit. It still often has slow response times. And they should load it up with a bunch more memory so it could pre-cache the next 5+ minutes of content. Both reducing HD access and allowing forward skip to be instant and not have the audio play delay. We should be able to press the forward skip button 6 times in a second and have it go 3 minutes ahead without any wait time.
Would be cool if they allowed for 4-way picture in picture. You can tune 3+ sat channels, 1 OTA channal, and play a recorded event. Why not allow 4-way PiP?
Hope they are planning on an upgraded unit that supports 4k up-scaling. Even today showing 2 1080i shows in PiP mode today would benefit from this. Since it will be many many years until there are native 4k broadcasts (like just a channel or 2, or downloaded PPV) the unit should up scale and be ready. This would also apply if they adopted 4-way PiP system. 4k would display each 1080p image natively.
Maybe some of this will Hopper Version 2
