There had been rumors of a whole bunch of new Epsons coming at Photokina, including perhaps two new 17" models... Right now, the 17" printer market seems pretty static, and the rebates and discounts aren't even all that good. Canon seems to have abandoned 17" entirely, although they technically still sell the iPF5100, it's now two generations behind the rest of their line. Epson has the 3880 (which uses an old inkset) and the 4900 (which seems to be the only truly modern 17" photo printer on the market, but it's huge - no lighter than the iPF6300, although a different shape).
I need a 17" printer primarily for sheet-fed printing, which is a huge pain on anything larger - doing a run of greeting cards or even 8x10 prints on an iPF anything or a 7900 is a massive exercise in frustration. I'd love to have roll capability as well, because I'm too mobile for a 24" or 44" printer right now (I've had them before, and will again when my life settles down). I like the 4900 except for the size, although I think I could manage it - it fits in the trunk of a regular car pretty easily, doesn't it? The 3880 (under 50 lbs, and relatively compact when folded up) is probably a better fit for how much I'm moving around right now, but the three year old inkset makes me hesitate (and I wish that 17x25" sheets were more common, because I like 16x24 as a print size).
I missed the rebates this spring that allowed a 4900 for $1100ish, and the best deals I see now are ~$850 for a 3880 (after rebate) and ~$1500 for a 4900. If I saw a 3880 closer to $650-$700 after everything, I'd jump on it (it would be worth it for smaller prints alone (the last bit of gamut doesn't matter as much on greeting cards or even runs of $35 8x10s), even when I own a roll printer again). A $1100 4900 would be very tempting as well, because it could put off needing to find the space for a really big printer for a while - I could send out the occasional 24x36, and the 4900 does 16x24s from rolls, and with state of the art gamut. If only the "3900" existed, it would be the perfect printer for my current needs (other than the lack of 17x25" paper).
