I just saw a great price for an Epson 4880. It is $899 after two rebates ($500 and $350) with free CONUS shipping. That is a heck of a deal so it makes me think there may be a new model coming soon. After all, the 4880 has been out for quite a while.
Here is the link to the place that has the deal. I have no connection to this company and feel sure you could probably get other reputable dealers to match the price or at least get close.
