It's not that part of Sony but rather the old Sony Ericsson (ie. mostly Ericsson people). It's still mostly the same people submitting from what I've seen in Gerrit. :)
Thinking like that, you should probably be more concerned that the NSA commits to AOSP. Granted, that's for SE Android though. The good thing about Android being open source is that you could revert any commit by some part you don't trust, as long as you have the ability to fix the issues that will arise.+Lorenzo Quiroli
Consider that the jump from GB to ICS was a jump from API level 9 to level 15 (2.3 to 4.0.3+) or from level 10 to level 14 (2.3.4 to 4.0), ie. you basically jumped two major versions. There also seems to have been quite a lot of changes to the kernel layer too which affects driver development. GB on the other hand was a jump of a single API level.+Raymond Rodgers
The CDMA carriers in the US don't seem interested to improve interoperability between them so I wouldn't count on it. That seems to hold true for the US carriers in general. Instead of competing with the quality of their service they seem perfer locking people into long contracts, carrier locked phones and incompatible standards or frequencies. That's how it looks from the outside at least. :(+Jean-Baptiste Queru
I know that you have no say in the matter but it would be nice to see multiband LTE in the next Nexus. GSM + LTE in general would be nice.
Also, it would be nice to either see samples of the bigram statistics file used as input for makedict or more official dictionaries. It doubt it would cost that much to buy/license a few more for Google.
Lastly, I think all Google apps should be upgraded with xhdpi icons. I doubt that would add more than a few 100 kb to the apk size and it really looks a lot better, as they should on a flagship device.
