4.7-Inch iPhone 6 Logic Board Equipped With Qualcomm's MDM9625 LTE Modem

The modem makes it possible. Now it depends on what Apple's switch and amp architecture is for the NA model.
TDD LTE on Band 41 is supported by the baseband chipset. The question is whether the North American variant will support it, or will they cram it up with Chinese/Asian variant (less likely).
What iPhone 6 won't support is Sprint's planned Carrier Aggregation of two 20MHz TDD component carriers. Obviously, Sprint's had many unfulfilled promises in the past, but one of their plans is to launch 2.5GHz intra-band Carrier Aggregation this year.
Considering that Sprint's TDD channel width is 20MHz, and that MDM9625 can support up to 20MHz of total channel width, the phone won't support 20+20 aggregated config.
It's good news for AT&T subscribers as their channels are 10MHz, so 10+10 or 10+5 will be possible. This will at least in theory even the playing field between AT&T and Verizon/T-Mobile as far as the peak data rates.

The 64-bit nature of the A7 is definitely exceptional in this case. However, the fact that, after more than two years of 1GB of RAM (starting with the A5X and continuing through A6, A6X, and both flavors of A7) and dual-core processors (started with the original A5 and continued through current A7 hardware), especially when applications could be written to (just like with applications in OS X) take advantage of quad-core processors, does make it seem like Apple was still being conservative.
Making a new hardware design with flaws (as has happened with the iPhone 3G, 4, and 5) is inevitable. That's different from, doing something different from what you've done for the last while.
Do you mean to tell me that a vast majority of iPhone customers haven't wanted a 4.7" screen since before the 4.0" screened iPhone 5 first came out? No sacrifices would've been required there. Though to Apple's credit, the iPhone is 52-54% of their incoming revenue; overshadowing literally all other products and services combined. Again, they are not being bold enough in some areas and history proves it.
I love technical discussion....but as soon as anyone starts in on the iPhone's 1 GB RAM....I have to shut off.
There are far too many reasons that have been repeated far too many times as to why the iPhone is more than sufficient with 1 GB of RAM.
For today's uses, I agree, it is sufficient. For down the road, I think it would help with the longevity of usefulness for all iOS devices as, there's a noticeable difference between my third generation iPad and my iPad 2 (yes I have a bunch of iPads), when really the CPU core is the same and the graphics are only beefed up to accommodate the retina display. RAM is the only difference. I think 1GB of RAM was a great move starting with A5X and then with A6, but at some point, so our iPads, iPhones, and iPod touches (if Apple ever updates that line) it makes sense to further update to 2GB.
I don't think 1GB is insufficient for today at all. I do worry about down the road with future versions of iOS though...
