...you can get RAW on the SX10 via CHDK. Or, if HD is a must, you could move up to the SX1.
Or you could go with the successor to the FZ28, the FZ35 (aka FZ38), but I personally prefer the vari-angle LCD on the Canon. But if you're willing to sacrifice the vari-angle LCD (which seems to be the case) as well as some zoom power for a more compact form factor (more convenient for traveling), you could go with the ZS3 (aka TZ7). Although, you should be aware that there currently aren't many 3rd party apps that can work with the AVCHD-Lite format that Panasonic uses in these cameras. This will probably change in the coming months, tho.
And finally, since you mention night shots, you should note that Canon's G11 has a slightly larger and more sensitive sensor than (I think) all of the above, meaning it will have better low-light performance. Probably not DSLR or even micro-four-thirds level, but better than the other compacts mentioned. No HD video, tho.
