How many pokemon do you usually have on your team during the first playthrough?
Do you learn as much as you can about the new gen before release, or let the game surprise you?
Do you nickname your pokemon?
1. Don't know offhand, don't really care to check, but I'd estimate somewhere in the 20-30 hour range. Obviously, you'd add on a lot more in post-game content, and repeated plays can shave off a few hours due to knowing what to do.
2. Five. Gotta keep an open slot for HM slaves or event Pokemon/eggs.
3. It varies. I researched a lot for D/P, just shy of pre-planning the entire team, but I tried to go in to B/W as blind as possible (managed to only spoil the starters, 2 towns, and maybe 4 other 'mons. Not bad, considering). For X/Y, I'll probably look up the new 'mons as they're revealed, but try to resist anything more than that.
4. Very rarely. for me, it's like an "all or nothing" deal, and I often don't feel up to the challenge of coming up with dozens/hundreds of unique and interesting names. Well... I say that, but I tend to only catch Pokemon I intend to use, and I hate switching up my team for any reason... so it's really closer to like 10 nicknames (including legendaries).
