I was more or less in the same situation as you are , 1,5 year ago, if I understand your message well. I actually do not expect that what you are looking for will be there soon.
Here is why;
You are in fact looking for a replacement for your G 800 and other equipment, to achieve MAJOR INPROVEMENTS on soundquality, with all the possibillities of todays arrangers and storage possibilities.

Allthough I agree with dave and fran that the G 1000 is a major improvement overall against the G 800, it is not a major improvement on sound.Sure there are some better sounds and more sounds, but it's nowhere near the quality(dynamic expression) of todays top synthesizers and sampled sounds.
Ofcourse this is a personal opinion and taste, so others might think different.

My experience;
Anyway when I was looking for a major upgrade I could not find any, and the G 1000 wasn't worth the upgrade for what it could do more, which basicly has to do with the way I use my G 800. If I had to gig I definately would have upgraded to a G 1000.
(f.i. loading styles thru a floppy won't work pleasant while playing etc...)
Then came the X1, psr9000 ....
Anyway I decided to buy a Kurzweil K 2600S, which absolutely is a MAJOR improvement with sounds, I don't even think there is an equivalent today.
But we are talking a lot of money as well, so it better should be good.
And it is not an arranger keyboard!
After a year of using the K 2600S here is a downer!
The sounds of the K 2600S are so good, that you can hardly combinate the different tracks with f.i. a G 800 or other arrangers.
( I had an X1 and a psr9000 at home for try out as well.)
It's like having a good band with a bad sounding drummer , a bad sounding violist, a bad sax player.
The sounds of the arrangers are just to "thin".
You think there's something wrong with the mix.

If you are a singer, entertainer, the arranger keyboards will do perfectly fine.
If you compose instrumental music, there are better options.

And ofcourse a professional can edit the sounds to make them more as what they are, but I like to play straightforward instead of editing and correcting sounds, in other words ready and go...

I don't know how the XV5080/3080 sounds are.
I never had a chance to try these.
I think Clif Anderson on this BBS owns one.)

I will have a psr9000 pro shortly for try out. ( I can borrow one from the local store)
but I don't expect it to be good enough..

Overall I think the arrangers are perfect for one man band's, but are a compromise.
(I guess they would be too expensive and un-saleable and not transportable if they were perfect.)

Others might think different, these are my own experiences only...
