The impression I'm getting from other discussions (do a search on the 1077) is that the 1077 will not be offerred by Ibanez in the U.S. in 2003. I think it's still being built, and sold in other countries as the RG2077XL. Sorry - I wasn't sure where you're located.
No official sources, to my knowledge, have said anyhthing about it, so the status of the 1077 is still a rumor. All I can say positively is that U.S. retailers do not have it.
My impression of the pups on the 1077 is that they are very close to Blazes tonally. The extended scale gives you a snappier, more percussive, more piano-like tone. The low string, for the same string gauge, sounds deeper and holds its pitch better. Higher strings do not sound as soft and round.
Holding certain chords can be hard at the low frets. Unless you use lighter strings, the added tension can make fast playing harder, and longer playing time can be more taxing. I have no trouble with that, personally.
