if the next elder scrolls game doesn't come out in the next year it will never come out.
Morrowind came out in 2002 and oblivion came out in 2006, daggerfall came out in 1996
although bethesda allows large spans of time in between their games, i seriously doubt, even with a strong fan base, that they won't be moving on to newer, (but not necessarily better) projects
I don't see that happening, it's even less likely it will come out this year since they haven't even announced it yet.
Let me post the timeline I made again, showing when TESV should be released if it follows Bethesda's normal pattern. I don't know if it will really work out this way, but it's just my guess:
