I haven't got any solid info on those launches, although maybe one of the WHFSV review team will have heard some more. But if Panasonic is launching new sets, you can be sure everyone else will too, what with 2008 being an Olympic year and thus a prime HDTV-flogging opportunity.
You could hold off buying forever - there'll always be something else new on the way...
We'll be attending the Consumer Electronics Show in early January - traditionally the time/place all the big brands announce their plans for the year ahead. We'll be bringing you live news updates from the Show on this site, and gathering as much info as possible on release dates, pricing and specs.
But Andrew's right, with another summer of sport due, i'd expect a wave of new sets due by June at the latest.
Lifecycles of TVs are getting shorter all the time - you're lucky if a particular TV is on sale for a year....
yep thats definately a danger - if nothing materializes in the way of news soon then I'll probably go with a PX70 as at that price I don't think you can go wrong and you're less likely to feel tied to it -- spent £1500 of Sony 32 FQ80 a few years back and although its a cracking set I'm sure I'd have replaced it by now if it hadn't cost so much.
