Aside from gaming with intense graphics, how do we know the WP7 OS needs better than the current generation of Snapdragon? It could run smoothly and you may not even care once it's in your hands. I think we should wait and see how the GSM launch devices perform before we call the 7 Pro out for failing.
Screen size is a matter of preference. Many people don't want anything larger than 3.6-3.7", especially for a device with a slide-out kb. The good news is that we could always go with a different manufacturer, seeing how all of them will run the same UI. I don't think HTC Hub will be anything too impressive during the first round of phones. I might actually go with Samsung for once. If dell made a variant of the Venue Pro for Sprint, I'd be all over that in a heart beat.
Also, it's likely we'll see something in slab form with a 4.3" screen from HTC around the same time. The EVO 4G has been a huge hit for Sprint, they would probably want to capitalize on something similar for their flagship WP7 device, don't you think? Maybe the specs will be upped a bit for that device.
Anyway, Sprint always gets dated hardware, that just comes with CDMA territory. Verizon is a little better in that department because they have Motorola. If you're looking to get devices with the best specs as soon as possible, you're on the wrong carrier.
I remember a lot of people commenting in forums and on sites this year that they wanted a TP2, but with a snapdragon... well, be careful what you wish for.
