I think generally each will influence the other, someone with a HDTV will want something to show it off, and would be more likely to buy a 360 on impulse and vice versa, someone with a 360 already will want to play it in HD.

I bought a HDTV earlier this year and must admit i do find the PS3 more attractive now, but not enough to buy one with its current line up.

Yeah I know, also being poor you have a lot more time to do sometting like watch TV. Not too mention a little something called the EITC that gives poor people $2-4,000 in February. More than enough for a plasma TV. Richer people are generally too busy with work and family and such to think spending over $1000 to get higher TV resolution is worth it.

 well i just dont see many people being able to afford HDtv's but i have seen widescreens that hhas been around since the 80's. and i still think that HDTV's are just a replacement for those old widescreen tv's. as for they are not droping in price like analysts had said 3 years ago. i know i have NO intension on buying one till i can find an HDtv for under 250 and i know lots of people like me. we have what is called a family with kids.

Just to piggyback on this, you can also view the poll results by country, and although you can't get exact percentages, the ratio in the U.S. looked something like 65% standard, 35% widescreen.  European respondents, especially in the U.K., were more likely to have widescreen TVs.

Numbers never lie, but you sure as hell can get the wrong impression if you don't know exactly what the numbers mean. 

i dont think the tv type determines what console people will buy considering most consumers are uneducated what they bought. All they know is they bought a nice big think tv they can put on the wall in their living room.

@Entroper: How can you view results by region? I may have not been familiar enough with viewing the statistics. Not have been so interested in it yet. :)
