I don't know about the next generation, but you can save around 10-20% on the current generation if you buy from Dell and use the various coupons that are almost always available.
I bought the Dell 1900FP (it's a rebadged Samsung 191T) 19" LCD a few weeks ago from Dell. It's starting price was $1299. I got it for $1024 shipped using a 20& off coupon, a $10 off $100 coupon, and a free shipping promotion, PLUS no sales tax to me in Cali! That's around 22% off, not including saving 8.25% more by not having to pay the sales tax. Can't beat that with a stick!
I say, "why wait, buy from Dell now"
