1080p looks better RIGHT NOW with 480i/480p SD, 720p, and 1080i, and will look even better with a 1080p source.
but in 5 years will a 720 set be obsolete? Like will events probably be only 1080p?
No, a 720p set won't be obsolete in 5 years (just as a 30-year-old Tube TV is not obsolete), but it will be considered old-tech. It will still work fine, but it won't look as good as a 1080p TV if you sit close enough to notice the difference, regardless of the resolution of the content you're watching.
im going to be watching lots of bluray on this 42inch..will the 1080p look better?
If you sit close enough, then yes the 1080p model will look better than it's 720p counterpart. Even if you sit further away, the 1080p model will have better processing and a more natural looking image. I have a 42" 1080p plasma that i watch from 8 feet, and everything looks better than it does on my 42" 720p plasma does at 9 feet (in another room).
What you need to do is measure off your exact viewing distance(s) at home, then go to one or two stores with a decent HD feed and compare the two resolutions. Find a 42" 720p Panasonic TH-42PX80U and also find one of the 42" Panny 1080p sets nearby. Walk up to within a few feet of the 720p set and look at the screen door effect so you know what you're looking for, then slowly walk backwards until the SDE disappears to the point that you can no longer see it. Measure off that distance and see how many feet you are from the screen. For some people it goes away at only 5 feet, but to others like myself with different vision i can still see it at 10 feet and i hate it. Now go do the same test on the 1080p set and i guarantee you you won't see any sort of SDE beyond a few feet. If you can see SDE within your viewing distance on the 720p set, then get the 1080p set. It's that simple.
