Tbh i would like 2013 to be side projects...allow her to have time with family and every so often a promo or announcement come out and circulate across the year and work on new material maybe in sessions across the year for a 2014 new era.
And then across 2014 do not go on tour right away...allow material to circulate, allow visuals/videos to have airtime/promo....do across the year a handful of big name gigs (glasto i am backing, V Fest is a potential, good morning america/summer circuit, NRJ Radio Festival/France)....she needs a bit more Eurocentric promo and to sustain the now regrown in strength US audiences/appeal and venture to do some special promo bits for Australasia/Asia

and really push it forward. And 2014 can then give album 13 longevity and then 2015 world tour....new material will be out there, she can space the tour over 12 months...new fans will have been brought in due to new material on circulation as well as the strong fanbase in millions anyway
But i dont think Madonna can possibly damage anything apart from the unpredictable start times...there are reasons for sure....and it has happened a handful of times but regardless she still broke and set new records with this tour despite the fact there were late starts etc.

I dont think its possible to damage a legacy when you are Madonna

but maybe it means they need more meetings about where to venture/head next and how they can space it all out
