This is exciting, but I don't think we will see every company jumping on the bandwagon just yet. We are missing some of the most key details, most notably: the price.
The reasons the R4 changed the flash cart market so much and caused all the other companies to jump on the bandwagon were the price and the ease of use. While this is clearly an advancement in flash carts (and one I am extremely happy to see taking shape), it will be quite a while before everyone else has one. Of course, if the price is nice and there are little to no usability issues, that could change very quickly, but there are reasons every other company hasn't cloned the iPlayer yet. We'll see.
PS: I'm buying one either way, tbh. XD
