To 1.5 or 2: That is the question **No spoilers please**

Greetings!
As I'm now on Chapter 7 of BG1 and playing the series for the first time, I'm wondering if I should wait until the Siege of Dragonspear comes out and play that one before I play BG2 for the first time, or should I play them in the release chronological order. Any thoughts? Then again, should I wait until SoD comes out so that you vets can get a better handle on it once you've seen the new game? Since I have no clue how 1 and 2 tie together since I haven't gotten there yet, I'd appreciate your opinions in the vaguest form possible.
Thanks!

On the other hand if I were in your position I would probably be champing at the bit for MORE!
On balance, if you have the patience, I feel it would probably be more satisfying to do the whole story in sequence.
But...
You could be the first and maybe the only one ever, able to play bg1' bg 1,5 and bg2 in this order!!!
You can make history!!!
Thanks for the great advice, guys! Keep it coming!

Icewind Dale happens more or less 1 hundred years before Baldur's Gate, on 1281 DR, whereas Baldur's Gate takes place on 1368 DR. Icewind Dale II I think takes place some 20 years or so after the first Icewind Dale.
There is no need to play Icewind Dale before Baldur's Gate, mostly no one did back then since it came after Baldur's Gate anyway.
Take into consideration that Icewind Dale is very different from Baldur's Gate since it's more of a Dungeon Crawl game and it's way more linear. There is no optional exploration for the most part, but the story is good, and it has many roleplaying moments. If you enjoyed Baldur's Gate strategic combat you will probably like Icewind Dale.
There're always many options to make another BG playthough, and then another BG playthough, and then another BG playthough...
BTW, @elminster and @Genryu can share their experience of playing not enhanced IWD2 on modern PCs.
What about Planescape: Torment, which is mentioned in the article you linked. Is this cannon to Forgotten Realms or another D&D world all together? (Sorry for my newbie questions.)
The simplest explanation I could give is that Forgotten Realms is a much more traditional setting (its what most people likely are familiar with when it comes to D&D) while Planescape is really out there (theme wise).
I'm getting very close to completing BG1, and intend to play through the whole Saga with the same character. Especially since the character that I've built this time around is by far the most fun and interesting that I have ever played in all my years with the Baldur's Gate games.
I suppose that characters in BG2 without any imported character, and importing from BG1 would remain the same.
In the case of SoD it seems you will import the entire party, and probably all the items as well, so it's a bit different, however, importing from SoD to BG2 will probably work as in BG1 to BG2, only main char and certain items (plus a few new ones from SoD).
