another data point
throwing in my successful data point here, but first thanks to all of you! i never would have found out about this otherwise.
1/x/16 first week - applied for first ever platinum select card. met the spending and got the bonus some time within the first 6-8 weeks.
2/x/16 last week - got converted from W to WE
3/19/16 - applied via link #15 but did not get instantly approved. called in and was immediately approved for a lower CL. shifted some over from card #1
3/25/16 - got the letter (was out of town, might have gotten it sooner) and it shows the bonus language ^
