Laptops will get better the longer you wait.
By the time the Haswells arrive, there'll be a newer thing on the horizon.
Question is if you really want/need it now. If you can manage with what you currently have, then there's no loss in waiting. If the marketing ends up being bull, you'll still be able to buy what you want at a much cheaper price.
This is the ongoing problem
I would worry more about
1) When do you need this laptop
2) How much money are you willing to spend
3) What do you plan to play
etc.
I would wait only if you feel whatever you were looking at now is not adequate for your purposes. There are certain crucial times to be careful, like buying a DX v.XX card shortly before the next wave of DirectX v.XY cards is a mistake I've made myself
Go for the new Haswell-based hardware if you don't require this until summer, I suppose.
But do keep in mind laptops with discrete GPUs will be your best performance option in any case. Mine doesn't get too hot (then again, it's got a lightweight AMD card, probably a fraction of the size of my desktop's)
