You can wait if you want but there's no practical difference between DDR2 and DDR3 from a user perspective. DDR3 tends to be slightly more efficient since it runs at lower voltages but there won't be any significant performance difference and you pay a premium for DDR3 memory. Intel's newest Core i7 processors and related chipsets require DDR3 but those aren't available for notebooks and it's not something you can upgrade any current notebook to in the future so it's really a non issue. The only reason manufacturers make a big deal out of it is to try to confuse you and make you buy their product.
You should be more concerned with the amount of memory, the speed and type of the CPU, the quality and size of the display, and other tangible considerations such as battery life, graphics card, keyboard, warranty, and even the general appearance. DDR3 vs. DDR2 should not even be on your list when shopping for a new laptop these days.
