Earlier today on Google+, Vic Gundotra posted a status update mentioning Sundar Pichai, who is currently leading the ChromeOS and Android team at Google, asking if he is also struggling to fall asleep.

In the past, Vic Gundtora has always teased major new updates to Google+ via a status update. This time, however, he has tagged Sundar Pichai in his update, strengthening the rumored October 28th date for the unveiling of the new Nexus devices and Android 4.4 KitKat. While this is just a teaser, it pretty much confirms it that Google will be unveiling the new Nexus 5, Nexus 10 and  Android 4.4 KitKat tomorrow morning (according to US timings) i.e. on Monday, 28th October.
