What tv should I be saving up for?

[Vincent Vega82]

I currently have a 60" 1080i Sony Grand Wega from 2004( http://www.sonystyle.com/webapp/wcs/...52921665087409 ). Although when i press display on the remote My tv's res shows as 1080i. Don't know if the 720p that that set is listed as shows up as 1080i when you press the display button on thr remote(the remote model # is RM-Y915) Would like it to be a solidly established model. No first gens, I wan't the bugs worked out by the time my model comes out. Hdmi 1.3 chip or better No side speakers attached(have surround sound and with the extra space saved I can get a bigger tv. (So no bigger than the width of my current tv 62" wide)I can start putting about $100.00 a month away. Already have $400.00 saved I want something that is at least 62". I would prefer a rear projection tv because, I'm going to keep the tv for 5-7 years so, when the light source dies I can just replace the bulb instead of having to buy a whole new tv plus I'd get the extended warranty. Are there any that are currently unavailable but, will be coming out w/in a close(1-2 years) time frame? Any suggestions for me?
Anyone know how much that 82" set from Mits will be.

I really wish Sony would get back into the rear projection tv's. They were my favorite.
