It´s too early to tell. This card was hit by the chip shortage, estimated delivery times here in EU begin with Mai. So it will take some time for Openwrt devs to lay hands on this. There is lot of ongoing successful work (for example RB5009) on other Mikrotik devices and the HW is fairly hackable. Anyway RouterOS is worth a try, it gives you probably much better performance than Openwrt. You can see a lot of comments like it´s being unstable and lacking features. IMHO that comes from the bad relesae timing by MT. They have released RoS 7 as stable in a state of rather being beta. It have seen lots of improvements lately. So until we can buy one Ros 7 will probably be OK for production use.
