what will have the most dev support?

[Hitch_Itch]

Im going to make the plunge later this month and buy a tablet.
My phone is a Dinc and its rooted and tweaked.
Im looking at the Asus eee Transformer, Acer iconia and the HTC Flyer

I do enjoy sense, but its smaller and only a single core cpu and the other two are running tegra 2 cpu

Im wondering what one will have the most support from the manufacturer for updates and if the devs are going to root them and tweak the heck out of them

Any ideas/info?

Thanks
Ken
