Given the length of time it seems to take getting a motor from TSR it's unlikely they'll be more than a flash in the pan. No doubt companies like Fantom and Trinity will match their performance and with the ability to actually fulfill orders rather than let lengthy back order queues build (while they have your $$ as well) people will switch. The latest and greatest means nothing if you can't keep churning out the orders in a reasonable time frame, one look at the TSR thread tells me that right now, they can't.
