Yeah, I think I will definitely buy the new iPad model coming out soon! I haven't bought the iPad because it is crippled: no video camera, no retina display, slow A4 processor, overheating, etc, etc.
The retina display is never gonna happen. Well, not for a couple of revisions. Why? Because the retina has a 4X higher pixel density than the current iPad's display. At 1024X768, a retina iPad will mean a staggering 2048X1536 pixels for the processor to work. Even desktop graphics cards have difficulty working with 2D at that resolution, not to mention 3D. The cost will also be much higher than the current cost of the iPad's IPS display. I also don't think that Apple will want to give developers ANOTHER display size to work with, original iPhone/3G/3GS and iPhone 4 and iPad is quite enough.
