Don't bother waiting. The only major improvements will be a front facing camera and probably a rear facing camera (not for sure). Apart from that, perhaps a speed boost and maybe s screen improvement, but no retina display yet for sure. It's not really worth waiting in indefinite amount of time for small improvements such as those, is it? Why bother? It could br anywhere from two moths to six. That's a lot of time to wait.
 
Just buy a refurb 16GB for $429 and flip it a week or two before iPad 2 comes out. You shouldn't loose too much if you sell it at the right time. I bought a refurb last week and plan to do the same.
 
What about the USB port?

I could care less about the camera option. What has me waiting is the various rumors speculating about a USB port in addition to the current port. If so, that would allow a Keynote presentation using the current port feeding a projector with the Keynote presentation on a USB stick or USB external hard drive.
 
Apple kept their iphone display for 3 years before they changed with iphone 4. I seriously doubt apple will change their iPad screen. Honestly, iPad screen is fine as it is. People are screaming for retina display, but that is just a hope.

Apple is not known for a company who throws in a lot of updates in every cycles. There will be updates and yes, apple will add camera, but everything else will not be significant.

Maybe slightly faster processor
512 MB ram
Gyroscope
Cameras for both front and rear

These features alone will sell iPad very well. Honestly, I don't care about any of these features unless apple tends to use them extensively. Original iPad still has a long to go, and I doubt I will jump into Gen 2 at all.

I will wait for Gen 3 or Gen 4. Probably Gen 4.
 
i bet the next iPad will have a faster processor or maybe even a dual-core ARM processor.
 
Just bought mine last night and I'm loving it so far. I was debating whether or not wait for the next one but I decided to take the plunge and don't regret it. I could care less if it has two cameras and if it's thinner with a different speaker place
 
I would wait, just because you know they will have some great new features in the new one that you will miss out on. I got my iPhone right before iPhone 4 was released and I feel like I really missed out.
 
I'd wait until they release the iPad that makes up your own mind about whether or not to buy. That, or wait for the one that helps you click in the search box at the top of the screen, since apparently the current one doesn't allow it:confused:
 
I would wait.
Personally those who are saying buy now and sell it and up-grade because they fetch loads now ................
If I was buying a second hand ipad after the release of the new one I ain't paying top buck, in fact you would have to give it to me.
