This is the latest update/rumour I know so far: 42009 Mobile Crane MK II has 2606 pieces and estimate retail at USD$220 in US. RRP expectation here will be (220 x 3 x 1.3) = RM850 before any discount. About RM800-900
Let me update my own info on first page.
8110 Unimog (largest Technic set so far) has ~2048 pieces.
That would be about an increase of 558 pieces 27%
Not necessary to have motor. You can do it in stages, which ever way you want first.
Some train sets come complete with basic tracks and all motorised.
Some with basic tracks only.
Some just the train only. (Maersk)
For display, you don't need to add anything.
But will be nicer if have track.
Then you may need like 5-20x (or more) boxes of tracks and huge area/room to lay out the tracks. Without motor, you still can push it around manually
By adding motor (battery pack, lights), signalling/control system, etc. that would complete the entire train.
LOL

I'm lucky I was sponsored as birthday gifts after I come back

Now regret I did not grab the 8043 set

Howevery, actually it is much better than going out to drink/smoke ... or worse find
chicks. You should explain nicely to her

Thanks for the very useful info on 42009. Any idea when it will be available here ? RM800+ is not that bad a price.
