The main problem you have now is your upgrade path is pretty complicated because the supported path would be Dapper>Edgy>Feisty>Gutsy which is a lot of effort (in reality it may be possible to skip some of those but the official upgrade instructions are pretty clear in stating that only an upgrade from the previous version is supported). I am hoping that there will be a direct upgrade path between LTS versions so you would be able to do Dapper>Hardy next April..But I wouldn't hold your breath on that being the case.
My understanding is that this is indeed the case - 6.06LTS -> 8.04LTS will be supported in a single step.
I couldn't find anything "official" in a quick Google but this is a start: http://www.mail-archive.com/ubuntu-server@lists.ubuntu.com/msg00756.html
"Hardy will be a special release in this respect since we'll be support upgrading from both 7.10 and 6.06. It is not trivial, but it's a high priority for us."
