You'll be waiting a long time. IPS on laptops is basically dead at this point. The market has spoken and no one really wants an IPS laptop (5 years ago this was different story). The problem with IPS is it's expensive to make. You'll rarely find an IPS monitor (any size) for less than $500, except when Dell does a fire sale.
Because laptop makers have stopped asking for them, LCD makers stopped making them. Until something else comes along we'll be stuck with TN panels. And they have slowly taken over each market. I've checked some online sites 20" is all TN, 22" has a few old IPS displays, 24" was split 50/50 before the summer, now it's down to 9 IPS out of 100. IPS is left at the high end. And that will eventually go TN, I believe.
As an owner of a LG IPS display I'm miffed that my next display purchase will probably be worse than the one I already have.
