I think we are in an unconventional promotion by design or by accident (probably both). Maybe these 4 singles are more part of a teaser campaign with releases of other actual singles ("I'm not a man"?) after that? I suppose on vinyl only would have limited impact on sales, only impact on the wallets of collectors/die hard fans.
I always assumed active promo would start after the US run of concerts with some US TV appearances on the East coast. Promo copies of the album are out there as mentioned by the Inrockuptibles guy so written reviews should also be imminent. I saw on Twitter that a special NME issue is also coming out next week
