Item Level - How high will it go?

[Roth_Trailfinder]

I do not expect item level to continue doubling. I would not be surprised, however, if it keeps going up, over the course of a 10 level expansion, by around 140 points or so.

And given that the item level display has 4 digits, I do not expect them to do anything regarding it (pruning it down or anything of that sort) until it is approaching the 10,000 mark. And at 140ish ilevels per expansion, I don't believe the game will have enough expansions to reach that mark.
