I've a good chance to sell my laptop within family for a pretty good price _now_ - tiger will be released around june?
Tiger is very likely to be available before the end of June. Current rumours put general availability around mid April.

Is it worth waiting for it?
Tricky question. Check out the features on Apple's web site and decide for youself. I would say probably.
The negatives
The iBook series are going to get less out of the new release than any other currently available Mac IMHO. The video card won't support some of the spiffier new tricks. Spotlight will in my opinion be hampered somewhat by the slower hard drive and processor (though still useful). The G4 won't see the benefit of 64bit native core.
The positives
Tiger is likely to show an incremental increase in speed over Panther. Some of the new APIs are interesting and useful enough that there is a good chance there will be at least one application within a year you would like to try that will be 10.4 and above only. Other little tweaks, such as the new Mail, Safari, automater, etc... Tiger is an evolution (mostly good) and by simply waiting a month you would not have to pay to get the benefits.

Will it be possible to upgrade pather to tiger?
definitely.

(are there any upgrade versions or can I just purchase a new version of mac os?)
Maybe, we won't know till Apple announces it though.
Personally I would wait till Tiger is released and see what Apple offers for systems bought after release but before Tiger becomes the default on all systems. I would then get it, if a free upgrade path to Tiger is available and wait till 10.4.1 or 10.4.2 was released to install. But I am a patient person.
