Basically Sony is realising that ASM2 kind of sucked and there kicking around ideas to try and save the franchise and one of those is bringing iit into the MCU continuity. Although I would like to see it happen the only way I could see it working creatively is another reboot. ASM 2 causes a lot of plotholes, given that those kind of incidents would probably of drawn one of the Avengers out of the tower.
