I agree with you, but at least they can sacrifice one or two songs from the latest album for some live debuts. no matter when, if they try to do it.
best example is the 2008 European tour, they debuted Valentine's Day and In Between way after the album release, but still while playing in support of it.
just rotate a bit of the set, that's all...of course not all singles can be played then, but still a big number of them.
