Just yesterday, we saw a leaked out version of the Gmail app that's coming to Android soon. It's a major refresh over the current version of the app as well. Which is a bit more colorful and has a bunch of new features. Google Keep was also updated yesterday, and got a bit more colorful like the leaked out version of Gmail. Now according to 9to5Google, it appears that Google is updating their own native and web-apps for 'Google 2.0' and an Android Wear push coming up in the next few months. Which I think is desperately needed. Many of their apps won't work well - as is - on wearable devices like the Motorola Moto 360 or the LG G Watch.
9to5Google's source talked about how Gmail runs in Chrome now:
"It doesn't have the feel of a traditional email client with folders/inbox on the side. It's like full screen email where they highlight one email at a time and you sort of cycle through them by snoozing them, archiving them away or deleting. I think you still can get a small list from a drop down menu of your emails but they highlight full screen viewing of each email."
It also appears that Google is going this direction with all of their apps on the web and on Android/iOS as well. Getting ready for the major wearable push with Google Glass, Android Wear and more. Which its about time Google really started focusing on wearables now that the smartphone market is basically matured.
We're likely to see a lot of these changes at Google I/O in June. Which we don't know for sure, but it's most likely. This year's Google I/O is taking place in the end of June so we still have some time before we see what Google has up their sleeves this year. Hopefully we'll see a new version of Android unlike last year.
