Well, I have an AVCHD camcorder and I love it, especially the whole ingest process. It really comes down to whether you would like HD 16:9 footage or SD 4:3 footage. I prefer the large frame sizes my AVCHD camcorder gives me.
Whether or not AVCHD is the future can be debated for countless hours. The undeniable present is in tape-based camcorders. One thing is for sure though, that SD DV camcorders are on their last legs. Soon the market will turn to only be HD camcorders, it's already starting.
It really is your choice. You might try looking into HDV cameras as well, because they shoot tape but they are HD. In the end, the real decision you will have to make is do you want HD footage or SD footage? Either way, you will probably burn onto SD DVDs.
Also, remember that HDV and AVCHD are transcoded to AIC upon capture/ingest resulting in much larger file sizes. If using one of these, it is a good idea to use an external drive to store your media.
If you're interested, you might have a browse through the HDV and AVCHD camcorders on the Canon site:

Several of these cameras (both consumer and professional) have quite large lenses that I'm sure you would be pleased with.
