I would hope that you release a full-length album. In my opinion it would be a shame if artists abandoned the idea of the album. I think an album is much more powerful and meaningful, an EP will always come off as being underwhelming. 

I think the music industry really killed off the album, with its absurd over-emphasis on singles. I know it used to be about singles way back when, but with the idea of albums being present for so long, why attempt continue on in that manner? Like, I understand why a band would want to have a single with regards promoting albums, tours etc. but when its all about the singles rather than albums, how can one expect potential listeners to care enough to buy the album? Even before filesharing took off, I always heard people say "I'm not going to buy an album because I like only one or two songs." And that mentality still exists, only now they really don't have to because they can look to any filesharing program and download those couple of songs that they keep hearing on the radio/TV. And how about when trite "best of" compilations are put together, it would seem to only discourage people from caring about the albums that the songs are gathered from. The idea of releasing albums still exists and when album sales are down, I still see almost no promotion for albums. But take metal music for example, a genre where there is no emphasis on singles, people primarily only care to listen to albums, from start to finish. Totally different mentality, and for the most part, they are the only ones I know who still actively buy CDs and records.
