We point out the physics opportunities of future high-luminosity B-factories at the Upsilon(5S) resonance and above. Currently the two B-factories, the SuperB factory in Tor Vergata, Italy and the Belle II factory in KEK, Japan, are under development and are expected to start operation in 2017 and 2016, respectively. In this paper we discuss numerous interesting investigations, which can be performed in the e(+)e(-) center-of-mass energy region from the Upsilon(5S) and up to 11.5 GeV, where an efficient data taking operation should be possible with the planned B-factories. These studies include abundant B-s production and decay properties; independent confirmation and, if found, exhaustive exploration of Belle's claimed charged bottomonia; clarification of puzzles of interquarkonium dipion transitions; extraction of the light-quark mass ratio from hadronic U(5S) decays; analysis of quarkonium and exotic internal structure from open flavour decays, leading to severe SU(3) symmetry violations; clarification of whether a hybrid state has similar mass to the Upsilon(5S) bottomonium, making it a double state; searches for molecular/tetraquark states that should be more stable with heavy quarks; completion of the table of positive-parity B-J mesons and study of their basic properties; production of Lambda(b)(Lambda) over bar (b) heavy baryon pairs, that, following weak decay, open vistas on the charmed baryon spectrum and new channels to study CP violation; confirmation or refutation of the deviation from pQCD of the pion transition form factor, by extending the Q(2) reach of current analysis; and possibly reaching the threshold for the production of triply charmed baryons. If, in addition, the future colliders can be later upgraded to 12.5 GeV, then the possibility of copious production of B-c(B) over bar (c) pairs opens, entailing new studies of CP violation and improved, independent tests of the CKM picture (through determination of V-bc), and of effective theories for heavy quarks.
