Ah well... I'll wait for the next upgrade then...
I think what is reasonable to expect from the new x880 with regards to improvements are:
1. Improved gamut (reds and blues) due to new magenta inks.
2. Improvements already included in the 3800:
a.Improved dithering and grain, with High Speed printing quality improvements.
b. Less clogging, at least judging from 3800 user reports.
4. Not much else....?
I really can't see the new series selling too well if you take the competition into consideration, basically because it seems the ink swapping issue has not been resolved.
Also, I think that it is reasonable to predict that the life of this series won't be too long. Another reason for someone not to upgrade or buy into the Epson line.
And it's a pity really as I am expecting that the printing quality will be state-of-the-art and usability problems and issues (other than ink switching) will be minimum (compared to what is being reported for their competitors).
The 64" 11880 seems to be another beast altogether. We'll have to see how it will compare to its 60" competition.
IMHO, the 3800 will remain a good buy for its target market.
