Hola Cern,
I admit I was torn, i cancelled my pre-order and was determined to stay away for a few months and pick it up on sale but then my impatience got the better of me and i bought it (think it was ?42 from greenmangaming). I had a fairly busy weekend so haven't played it enough to say if reviews are right or not but it doesn't seem terribad (the character animations are sometimes very noticable, sometimes not). Story wise hasn't really got going yet for me but I'd suggest they were up against it anyways having to create a whole bunch of new characters.
I only tried the multiplayer once, but it seemed allot like ME3. In fact, very similar to me - waves after waves of enemies etc. They also say its optional and you can send NPC teams out to do the missions as well, doesn't seem to be as important as the 'war effort' was in ME3, but I'm not sure yet.
In short, if you can wait until it's properly discounted (maybe November for thanksgiving?) then I'd do so. I was too impatient

I know eko got it too and he's a bit deeper in than me I suspect, so I'm sure he'll post soon also.
