What happens to our iLevels?

[Galliano]

Does anyone know what this means for our current iLevels? With the level cap increasing to 60 and likely the end game iLevels being higher then 135, what happens at 51 or even through 59? Can we expect our WoD, BCoB, Poe and Zodiac gear to become useless right away or what?

Im not tring to cause a panic or complain, Im just really curious as to what will happen with gear levels.

Well given that each major patch we've had so far has outdated the previous patches gear, I think it's safe to assume the expansion will do the same.
