DW the PIE bus stop is around 5-6 mins walk from blk 16-19 jln tenteram (opposite the BTO) that got 3-4 buses to toa payoh, but from toa payoh to there you have to alight at the PIE bus stop opposite side, and cross over to tenteram side, this one around 8 mins walk from the bus stop to jln tenteram. The buses are very fast because it's in PIE. As far as I know, no jam at jalan bahagia / whampoa. Balestier road is crowded and sometimes jam if you are coming from that direction, but if coming from CTE, just exit at Jalan Bahagia, and I'm home
tofuguy nothing announced yet, some say might have Seletar Line at Mar Thoma (literally just cross CTE via underpass from the BTO - 5 mins maybe). But I think it might take sometime (if the plan is real) in 202x to complete, now with so many MRT lines in progress.
Looking at the take up rate, is it possible that the BTO will be cancelled?

I have mixed feeling for it as it will be noisy with the BTO going on... and less greenery too. But more neighbours normally means more amenities coming
