Not sure about last full album tour, but U2 so you never know.
What is curious, intriguing, whatever word you want (and likely the subject of many future threads) what's next after this tour from a tour perspective?
u2.com shows 360 ending in '11, I&E '15, JT30 in 2017... the sort of standard 4 to 5 years puts the next tour in 2021 ish... that's a long time away.
Or, reboot I&E on a shorter time frame say late '18 or '19... and if that's the case, that's a lot of touring for a band that has historically put at a solid 3 and frequently 4-5 years on between tours... plus a bit of market saturation... at least for some parts of the globe.
