I would guess the video is meant as a teaser, rather than saying look at our new stickers.
I'm with you SLC, more of a teaser than a launch video.
I know GM have actually got their full 2015 stock out in the UK already (well bats anyway), but M&H is a smaller brand so makes sense for them to be a little bit behind.
As for the rebranding, lets be honest about other brands. With the exception to the ugly GN Nemesis, most of the large bat manufacturers release the same bats every few years under a new name to re kick sales.
In this case, M&H have at least been honest to the foundations of the stock that have made them the company they are. Change the name for 'Original' to 'MH87', retains the origins of the bat you're buying, but brings all their branding into line with that of the CK22 they released in the last few seasons.
In reality, they are doing very similar to what Gunn & Moore did. They released new models with the Zona and Six6 with new decals, and have now updated the rest of their range to match.
My understanding of M&H (having not owned one myself), is giving cricketers continuity between bats. If you had an Amplas three seasons ago and want a new one, its pretty easy for a reseller to be able to remember the Amplas is now the MH09. So, I believe they are actually respecting their returning customers, which is nice to see.
